Nothing I am aware of that you have to join Shaggy for. I joined there right after the Bama-Texas title game because of a link from RollBamaRoll. It was a hilarious MSPaint thread about a Texas fans experience at the game. I am in the top 5% in rep there but not because of butt kissing, I have told them they were full of it about the "If Colt hadn't got hurt" but not in a trolling way. I just explained to them that they have no way of knowing what the outcome would have been. They could have won or they could have lost worse. I have stuck around there because it is a very active board and they are more active on all the other boards. The Football board is maybe 5% of all the posts there. Other than Asylum and the good info on RoR, Woolly was mostly Football only discussion. Hopefully the new and improved Woolly will bring more people in, so we can have a wider range of discussions.
As a bonus, my being there caused me to create Woolly. The downside being that it also eventually allowed AHM to backchannel his way into shutting us down temporarily.
