I'm glad the council suggestion seems to have died a death. Given that moderators ARE members I really can't see the need. I mean, look what Ollie's doing here - inviting and discussing suggestions from members. And a council would... invite and discuss suggestions from members, before having to pass those on up to the moderators anyway. It is a thoroughly pointless idea, wrong in principle and with no real arguments in favour, that also introduces extra problems.
I agree with having popup PM notifications (and can't stand the logo, but that's another story) but otherwise I can't actually think of anything wrong with this site!
