Forum Moderators: rogerd
I find it interesting that this promotion is working for you. May I ask if your forum members (new and old) are very young? The reason I ask, is that your top prize of $10 would not motivate me personally to post like crazy on a forum. No I'm not wealthy (not by a long shot), but I do value my time more than $10.
On a side note, on one of my forums I'm running a silent "contest" along similar lines. I'm planning to send my top 10 posters a little (branded) gift at the first of the year. The difference being the members have no clue. Not good for driving traffic but perhaps will enforce some loyalty later.

The trouble our forum faces is the number of lurkers, only 10% of members actually post so I'd rather have fewer posts from more members that loads of posts from the same few people (who are mostly moddys anyway).
