The Avengers Alliance Wiki does not have a customized message above their chat. If you are referring to where it says Marvel: Avengers Alliance Wiki, that is the wiki's name. The two elements they *can* customize, they don't.

Or are you talking about the Wiki Navigation? The "On the Wiki" navigation bar? That would be MediaWiki:Wiki-navigation, also accessible via the Contribute dropdown. Both ways require admin rights. BTW, the "On the Wiki" level itself cannot be altered.
