Admin Forum:Changing chat welcome "WCDDoherty has entered the chat"

I was wondering how to change the default chat message on my wiki--WCDDoherty 02:29, April 16, 2012 (UTC)
 * Edit MediaWiki:Chat-user-joined to change the message everyone sees when someone enters. You can find a list of chat-related messages at http://[WIKINAME].wikia.com/index.php?title=Special:AllMessages&prefix=chat&lang=en. You must be an administrator to edit any MediaWiki pages.
