how about for the newbie? i think there's should be a "Most Helpful Newbie"...?
At another forum I frequent, they have a yearly "Member of the Year" contest. Each member can nominate up to five other members. the voting runs for about four to six weeks. At the end of the time period, the votes/nominees are tallied, and a winner declared. In case of a tie, there is a run-off. Each winner can only win once; they can never be nominated again.
