BluefireFlames: "Oh great, talk pages don't give notifications anymore." You mean talk pages that are a substitute for the message walls comments? If so, actually yes they still give notifications. However the notifications can only be seen when you are on a UCP wiki, and is not seen on a legacy wiki (and vice versa). If that be of any help to you.

Boyariffic: That's pretty much what I think as well. It's unthinkable to force the migrations of the wikis, with the possibility of breaking up whole wiki communities because of the numerous bugs that have yet to be fixed.
