Because your username is our unique way of identifying you, you can't change it. However, you can sign out and register as another user name, but you'll lose your personal topic list, so save it first (File->Save in your browser's menu). To register as another user, sign out, click the sign in link, submit the form without a password, then click the register link on that page, erase your current name and type in your correct name and go from there.

No, it is not currently possible to change your user name after you have registered. This would be extremely confusing to others who have you on their contact list, especially if later someone else were to register with your old name.

Assuming that $wgPasswordSalt is set to true (the default), you can use the following SQL query: UPDATE user SET user_password = MD5(CONCAT(user_id, '-', MD5('somepass'))) WHERE user_name = 'someuser'; Where obviously "somepass" is changed to the password you want to set and "someuser" is changed to the user name as it is listed in the table "user".

Go to "My NDEI" and click on the "My Profile" link. On this page, you can change your Password. User Names cannot be changed once entered into the system. If you would like to change your User Name, you must re-register.

Passwords are changed on the Edit Existing User screen (see above). If you have included the person's email address, the control panel will automatically send new logon instructions by email. Changes take effect immediately.

The control panel will let you change a person's full name, password, and email address, but not the username. To change the username, you must delete the existing user and create a new one using the new name. Visitors can't be two people at once. The visitor's browser will submit user information for every access to the server. If you are pulling content from areas with different user restrictions, the browser will suffer split personality, and the visitor won't get to see the content.

The user interface text is put into pages in the special MediaWiki namespace. When logged in as a sysop, you can edit those pages to immediately change the output of the wiki. Some configuration changes (like changing $wgSitename to set the wiki's name) don't affect the pages which were generated at install time. You can edit them directly, or use the "rebuildMessages.php" script in the maintenance directory (it must be run from the command line and you must set up an AdminSettings.php file).

The MediaWiki default user preferences are in the language file, i.e. languages/Language.php if you're using English. Don't edit that file, just use it for reference, like you do with DefaultSettings.php. Say if you want to change the default number of search results on a page. Language.php says: /* private */ $wgDefaultUserOptionsEn = array( ... 'searchlimit' => 20, ... ) To change it to 50, put this in your LocalSettings.

You may change your user password on the User Account Information screen. Click Update User Account on the Options screen and follow the instructions. If you are the Entity Data Bank Administrator and wish to reset a user's password, highlight the user's account information on the Maintain User Account Information screen and click Reset Password. On the User Account Information screen, you may reset the user's password.
