Hello, Mathmagician, a while ago you posted in the forums about whether or not one can test whether Message Wall is enabled. I just happened to be rebuilding my signature, yet again, and &mdash; just in case you don't already know this &mdash; I discovered that one can use  now! Okay, it is a little hit-and-miss, but it works 100% on MediaWiki 1.19 wikis now. It also sort-of works on the 1.16s.

For instance, if you were on a 1.19 wiki and left a parser functioned signature &mdash; I'm assuming here that this was all about sigs? &mdash; the system would recognize the difference between your old User_talk page and your Message_Wall page. So even if you're on a wiki that has just changed over to Message Wall, and your old User_talk page has been archived,  will still display the Message_Wall link &mdash; not the User_talk red-link.

However, on MW 1.16s with Message Wall,  would find your archived User_talk page and attempt to link to it. This isn't a huge, nor permanent, issue, since the viewer is just redirected to your Message_Wall page.

My apologies for explaining all of this if you already know; I just wanted to make it clear as to what I'm on about &mdash; it's been over 100 days I know. :)
