As stupid and possibly degrading as it may or may not be, I think that it makes sense for this board given the demographics, the way that women tend to be discussed, etc. You have to keep in mind that this is ALL stupid and just for fun. But if you can't distinguish between this award and the other awards that you suggested ironically, given what you [should] know [by now] about this board, then I think perhaps that you're just barking up the wrong tree and creating a problem that doesn't really exist. Maybe the inclusion of a best Male Poster award should be included just so people would stop whining, but in that instance, the qualifications for the gender-based awards and the overall "MVP" award would have to be distinguishable, otherwise it's inevitable that one of the winners of the gender-based ones would have to win the overall one.

nuncheon and Winter seem to have "mysteriously" scampered off...I have no idea why.
