Changing Your WordPress Multisite Admin Username – Network Admin
No doubt you found and followed some tutorials to change your admin user name, you most likely found some old MU tutorial and then found that your new WordPress 3.1 Network Admin menu/area just disappeared.
Well this quick set of pointers should help you out! 
Log into your PHPMyAdmin or what ever you are using to edit your database.
1. Find the table “_users”.
2. Edit the row where the “user_login” column is equal to “admin”. Change the admin part to what ever is your desired user name.
3. Also edit the row where “user_nicename” column is equal to “admin” (same as above) Change this to your desired “nice” name (no spaces or such) – This is also used within BuddyPress for the profile link and @admin.
4. BuddyPress users will want to change their profile where it echoes out “admin”, this is located in the table “_bp_xprofile_data”.
Now you will most doubt have done all that but now can’t find the “Network Admin” link and section, well you need to edit one more thing:
5. Open the table “_sitemeta” There is a row “site_admins” with data under the column “meta-data”, it will look like this:
a:1:{i:0;s:5:"admin";}
You will want to change this including the number 5 which is the character count of your username, so in my instance it will look like this:
a:1:{i:0;s:3:"tim";}
Save and test it out, that should fix the issue for you.
Please note: There could well be other instances in the database on a multisite install, I haven’t thoroughly checked. I only worked through this to help another user find a solution, this worked for me and then worked for them. Always make a backup of your database first!
Hopefully this should help someone out there! 
noreply@ wordpress@ Ripping Your Hair Out And Want To Change These?
You might find these when using BuddPress, Contact Form 7, WPMUDEV Supporter Form and no doubt it annoys you!
First of all if you are runing a vanilla install of WordPress you will have no doubt noticed that when system e-mails are sent out that the address is usually wordpress@yourdomain.com and of course you could most likely find a plugin to combat this but is a another plugin bloating your install really what you need?
So, where can you change this in the core code?
/wp-include/pluggable.php
Around line 391:
391 | $from_email = 'wordpress@' . $sitename; |
Around line 1057:
1057 | $wp_email = 'wordpress@' . preg_replace('#^www\.#', '', strtolower($_SERVER['SERVER_NAME'])); |
So that is the default out of the way!
Now you are running BuddyPress and you notice that your “Contact Form 7″ or Supporter form is sending out e-mails with a sent address from noreply@yourdomain.com, of course this is damn annoying, it makes it more time consuming when you make replies, often you send an e-mail to yours noreply address and then get angry clients asking why you haven’t contacted them back, or if you use a support desk so you can’t just reply to that ticket. Its most annoying when all you need to do is reply yes or no and especially so when using the supporter form for your clients.
So the problem! It is actually buddypress causing the issue here. At least in 1.2.8 (Not checked other versions) You see it ads filters to the default WP_Mail function forcing its own headers. What you need to do is remove those filters and everything will be back working as it should.
Contact Form 7, Add the following:
remove_filter('wp_mail_from', 'bp_core_email_from_address_filter' ); remove_filter('wp_mail_from_name', 'bp_core_email_from_name_filter');
In the compose_and_send_mail() function around line 693:
693 694 695 696 697 698 | function compose_and_send_mail( $mail_template ) { remove_filter('wp_mail_from', 'bp_core_email_from_address_filter' ); remove_filter('wp_mail_from_name', 'bp_core_email_from_name_filter'); $regex = '/\[\s*([a-zA-Z_][0-9a-zA-Z:._-]*)\s*\]/'; |
Now it will use what ever you stipulate in the admin area of Contact 7 which is usually the e-mail address for the person contacting you!
And the WPMUDEV Supporter plugin, open the following:
/wp-content/mu-plugins/supporter-premium-support.php
Add it to the supporter_support_page() function which is approx. line 94 it should then look like this:
94 95 96 97 98 | function supporter_support_page() { global $current_user; remove_filter('wp_mail_from', 'bp_core_email_from_address_filter' ); remove_filter('wp_mail_from_name', 'bp_core_email_from_name_filter'); |
You could if you wished wrap it up in some conditional statements to check for BuddPress first, but for me it is always installed, at least for now!
If you are not using BuddyPress or you still have this issue after removing the filters then chances are there is another plugin or even theme which is forcing its use of the wp_mail() function.
Note: One thing to remember is that making changes directly to the main files of WP, a plugin or theme means that when you come to upgrade you will need to remember to make those changes again! I prefer this over bloating an install with plugin after plugin.

They were recently hacked and now your details may have been exposed.
Winamp Management Team — On February 11, we discovered that the Winamp Forums (forums.winamp.com) servers were compromised, resulting in a security breach where Winamp Forums users’ email addresses and passwords may have been compromised.
We understand how important trust is, and we’re deeply sorry for and embarrassed about this breach of security. We immediately closed the exploit that led to this compromise and we’re working around the clock to ensure our security moving forward. We’re also committed to communicating openly with you to make sure you understand what has happened, how it may or may not affect you, and what we’ve done to fix things. If you are a registered Winamp Forums user, you should have received an email from us notifying you that your account may have been compromised.
We have confirmed that this attack was isolated to the Winamp Forum (forums.winamp.com) site only. Other Winamp sites and products such as Winamp.com, dev.winamp.com and the Winamp Desktop Media player were not affected in any way.
We have prepared the following FAQ for questions you may have about this incident. If you have additional questions please feel free to contact us at support@winamp.com.
1) How do I know if my password was hacked?
If you’ve registered an account on the Winamp Forums (forums.winamp.com), then it’s best to assume that your username and password were included among the compromised data.
Passwords in our database are encrypted (i.e., not stored in plain text), but they may still be vulnerable to hackers. You should immediately change the password on your account, and if you used that password on any other web site, you should change your passwords on all of those accounts as well.
2) What data was exposed in this breach?
We have confirmed that your email address was exposed as a result of this attack. We have not confirmed but must assume that other Winamp forums user account detail, including your forums username, date of birth, time zone preference and password hash (not your clear text password).
3) Should I be concerned about my other online accounts? What if I used that password on other sites?
If you used your Winamp Forums (forums.winamp.com) password on any other web sites, you should change the password on those sites as well, particularly if you used the same username or email with that site. To be safe, however, you should change the password on those accounts whether or not you were using the same username. We’ve put together a guide to help you audit and change your passwords.
4) How can I delete my account?
We understand how important trust is on the web, and some of you may wish to delete your Winamp Forums account. To delete your account make sure that you are logged into the Winamp Forums and follow these simple instructions:
Scroll down to the bottom of the forum home page and click on ‘View Forum Leaders’. Scroll down to the Root section to see the list of Administrators. Send your deletion request to DJ Egg or DrO using the contact link to the right of the administrator’s name. The Administrator will delete your account upon receiving the private request message.
5) How do I change my password?
You can change your password in your “User Control Panel” settings. Log in to your account, click the “User Control Panel” in the Forum Nav, then click “Edit Email & Password” under “Settings & Options” Enter your old password and your new password, re-enter to confirm new password and click “Save Changes.” Your password will be updated. You can also change the email associated to your Winamp Forums account on the same screen.
6) What if I forgot my Winamp Forums password?
On the Login screen attempt to log in once, after you fail one login you will see “Forgot your password? Click here!”. Enter the email associated to your account and text/numbers in the image verification box (aka Captcha). You will be sent an email at that address that will reset your password. Follow the link you will be taken back to Winamp Forums and another email will be sent to the same account. Use that username and temporary password to login. You can reset your password now by going to the User Control Panel. See instructions in #5 above.
7) Who was responsible for the security breach? How did it happen?
Our security team was able to identify and block access to the application flaw which resulted in this breach. The application was patched and new security measures have been deployed to keep this type of breach from happening in the future.
How are you notifying those whose details were compromised?
We are in the process of notifying all users with a registered account for the Winamp Forums via email. Please feel free to forward these FAQs to anyone you know who uses Winamp Forums. We can also be reached at support@winamp.com
9) What are you doing to ensure this doesn’t happen in the future?
The security team has introduced new web application protections and monitoring processes to detect abusive activity.
10) What should I do now?
You should change your password as soon as possible, both on the Winamp Forums and on any other site where you use that password.
11) When did you discover the breach had occurred?
We discovered the breach on Feb. 11. We actively monitor Winamp Forums and all Winamp products via a rigid security plan and software that alerts us whenever there are attempts to breach that security. Those processes alerted us of this breach and we reacted within 24 hours and shut down the exploit.

Yes, we sent an email on February 15 to all Winamp Forums users informing them of this breach and asking them to reset their passwords for the Winamp Forums and any accounts where they use the same email and/or password.
