I was staying away from the sig hack. We already have the avatar on the side, and I think it's neater without sigs.
What *might* be possible, if people insist, is to add a self-editable text field (not too big) to appear below the avatar?
Ah, yes, the post count - will get onto that soon.
Didn't look at the PHP site to be honest - there's too much left to do as it is. Will maybe take a look at a later date when most of the other stuff is sorted.
