I hope I'm not out of line by sharing the contest we have on our site with you here. We are trying to come up with a contest to increase traffic on our forums but this one is kind of a fun contest, not to hard. If you enter at this point I'd say your chances of winning are pretty good as we have just started it.
If you click this guy,

on the
page, it explains what to do. This seems like a good time to say thanks to
Misfit Toys for providing our first prize.
The problem with many contests geared towards driving users to a forum seems to be that it promotes only more post, but does not address the quality of the posts. It seems like it's more important to get quality posts, not just quantity. Any ideas on how to accomplish that?
