With the "View Source" option ticked and using the Monobook skin (I haven't tested on the Wikia skin), you can click the "View Source" link on a message multiple times, and get a "Done" button for each click of the link (nothing weird happens with the display of the message itself, though; you just see the source as you would expect). Clicking any of the buttons causes them all to be removed and the message to display as normal.

Also, there is no talk namespace defined for the "Message Wall Greeting" namespace, so clicking the "discussion" link leads to the articlespace page "username" (e.g. the "discussion" link on Message Wall Greeting:Dinoguy1000 points to Dinoguy1000). Either a talk namespace needs to be defined, or the discussion link disabled for this namespace.
