I will also vote for Peter as the 'most helpful.
I reckon just an all round nice guy (among many, of course)
Peter, I will send you the bill later
Most annoying : haven't come across one I would vote for that yet. A couple from the past come to mind (hint: rice and kings are items etc that speak to me).
However, wont commit, at the moment, but definitely wont put a vote in for Gary.
Gary, your bill will follow as well
Best Portrait : I am going to nominate Daacon, (Dave). I reckon that avatar with the goggles and snorkel has to be an absolute classic!! I assume its a self portrait, it would be anybody's guess?
