Also, admins should at least be able to remove messages from other people's Message Walls, in my opinion.

That said, I'm not too fond of the idea alltogether. As another user said, the system looks too alike Facebook, and I think it strays too far from Wikia's primary purpose to be a database. It's getting too primarily based on the community, in my opinion.
