This is not easy. I may well miss out on some deserved nominations with these selections, but here goes:-
1.Most vital poster: The Original Spurcat. Despite the couple of run-ins I've had with him, I have to admit that he does come up with some useful information that no one else seems to have access to. Spurf ran him a very close second, though.
2.Most respected poster: I believe I voted for Spurf last season, and I think he tips it, again. This was a close vote, however, and I have King Hotspur and PNP very much in the running.
3.Funniest poster: SpursDisciple and Notso always crack me up
4. Most grumpy: Jesus! How long do you want the list! Anyone not jumping on my "mighty Spurs juggernaut" is a grumpy bastard, in my view

GHoddle10 probably tops the list, though.
5 Most Optimistic: I think most of us are optimistic in some way or other, as even those whom I would consider most pessimistic can usually manage to find something positive to say about the team/manager. SpurLock is the one I would nominate, though, simply because he has been on board with the whole AVB thing right from the off.
6 Most Pessimistic: Spurs or Sex and Canary Spurs, for me.
