Since the criteria for poster of the year hasn't been defined, I'll provide my votes via categories that would "seem" to be good criteria:
Most Knowledgeable - Plaino...no contest.
Funniest - K2C...no contest.
Wittiest - Fitty...no contest.
Nicest - Senior Sooner...no contest.
Toughest - Iasooner...NO contest.
Me tough, bwaaahaaahaa... uh no; I used to be a lover not a fighter. Might wanna replace that one with 22 or Schoonerman.
