Do you mean when the user first edits they get a welcome message, and a defualt user page? If so see:
 * MediaWiki:Welcome-user-page (the default user page)
 * MediaWiki:Welcome-message-wall-anon (the welcome message for anonymous users)
 * MediaWiki:Welcome-message-wall-user (the welcome message for registered users)
