I don't think what you're referring to is what's contained in MediaWiki:Chat-default-topic. If it is, then just add whatever you want to that page. For instance if you wanted a link to the rules: Welcome to the $1 chat! Please click here for the rules. Would do the trick. However, that's the message you would normally see in grey in the chat window as you join.

I think you're referring to the somewhat heavily customised chat some wiki use, such as the chat header used on call of duty wiki's chat which currently contains Welcome to the Call of Duty Wiki chat. Rules and more information can be found here. FAQs here. Chat statistics. Emotes list here If that's the case let me know and I'll dig out the various additions you need to add that.
