As a "name" an IP address is somewhat clumsy. Also, if you use computers at different locations (home, office, internet cafe, etc.) you have a different IP-address in each case; even in the same location, depending on the Internet connection, the IP-address may be different each time. Therefore a username is better to maintain an identity.*You will establish have your own ''user page'' where you can write a bit about yourself, and a ''user talk page'' which you can use to communicate with other users.* You will be able to mark an edit as minor, which avoids inconvenience for other users.

Also make sure your computer's date and time are set correctly; if they are not, cookies may expire before they are supposed to. In addition to these steps, check to prevent impersonationmake sure PHP's directory for storing session data is writable. This directory can be found in the php.ini file under the session.save_path setting. If you log in and enabled the cookie feature, a subsequent log in as a different user without the cookie feature enabled will appear as logged out. == How to set preferences == Click on the ''Preferences'' link at the top right of the page for various options, including:* Changing your password.* Changing the ''skin'', which changes the way that the web pages look. See [[MediaWiki User's Guide: Setting preferences]].
