@merc, yeah I know this post has been edited is annoying, I do a lot of after editing, but it does ensure integrity... I suspect some users when in a conversation won't stick to their guns as it were and then edit their posts to reflect somethign totally different.
I think, although annoying, the edited by is quite essential. Post count on the other hand is quite retarded and extremely misleading in so far that there's a totally daft association that some one with a lot of posts is somehow better than someone without, or has 'done more' or something totally unconnected
As said post counts are still there, it simply isn't presented on every post as if its some kind of 'elite status'
