"make 50 posts in the next 2 weeks. "

You know the problem with that?? Many people are basically going to spam flood ur boards with junk so they can get entered into this drawing... In the end you have lowered the value to your boards by burying the good content with all the spam.

I see you want to increase content/traffic, but I would recommend a different approach maybe. Such as top 50 posts entered into random drawing, etc...
