You Need To Change Your Username Or you Will Be be Blocked
[edit] Instructions
First, take a look at the username policy to make sure the username you are requesting is appropriate. Also, please note that for technical reasons, your username cannot begin with a lowercase letter, nor can it contain any underscores. 
Check to make sure the username you are requesting is not already taken. Do this by searching for the name in this list. If the name appears in the list, even if the link is red it is taken. Do not create an account under the new name. We'll do that for you. 
Log in with your present username in order to place your request. Renames will not be approved if the requestee is not logged in. 
Click here to place a request. 
Replace the text "CURRENT" with your present username. 
Replace "NEW" with the username to which you wish to be renamed. 
Fill in a reason where indicated but do not add anything in the "subject/headline" box. 
If that doesn't work, simply copy the following text to your computer's 'clipboard': 
 CURRENT → NEW 

 Reason: Reason for requested renaming.   
Go to the "Requests" section of this page, click the "edit" link, and paste the text at the very bottom. Modify it as indicated above. 
Make sure that you have spelled both names correctly. Save the page. 
Check back periodically to answer any questions that may arise regarding your request. Do not be surprised if you suddenly cannot log in to your old account; this merely indicates that you should log in under your new name as the request has been fulfilled. 
Please be patient. It may take a few days for your request to be completed. 

Effects of a username change 
When the rename has been completed, your account will have been renamed, and any contributions you have made (including deleted contributions) will be reattributed to your new account as a background process. Your account preferences, watchlist contents, password, etc. will all be preserved, and your user and user talk pages will have been moved to the new name. 
Note: The process responsible for reallocating old contributions is currently dependent upon the job queue mechanism. As such, you may find old contributions do not immediately appear under your new account; this is perfectly normal. Updates should take at most a day to complete, although the length of time will vary according to the size of the job queue on this wiki, and the status of the server processes which process this queue. 
The change will appear in the user rename log and the request will be moved to the archives in the interest of transparency. It is not possible to rename accounts without an entry being created in the log. 
This change will not affect signatures you have already left on talk pages, or other places where you signed your username with   . Those pages will continue to display your signature (including the link to your old username) unless edited manually. 
Be aware: Once you have been renamed, your old account will no longer exist and may potentially be recreated by a third party. This is true even if your old account pages have been redirected towards your new account. To guard against impersonation, you may wish to recreate the old account yourself.
