Can you identify these GW autographs?

I've had this poster kicking around for a while, sitting in a cupboard for the last several years, and thought maybe its best I just find it a new home.

I figured I'd at least TRY to get it a new home before just chucking it.

So, its autographed by a handful of GW (some former) creatives, but I now don't remember/recognise most of the autographs on it. I think it was done at a Games Day, and there were just people around.....

Anyone want to have a crack at it?
