MediaWiki:Welcome-message-user and MediaWiki:Welcome-message-anon should be edited for wikis with user talk pages while MediaWiki:Welcome-message-wall-user and MediaWiki:Welcome-message-wall-anon should be edited for wikis with user message walls. Also see Help:Welcome tool.

Link to the templates if they are still a problem.
