You guys will have to tell me if you think these are worthwhile to host, and if you'd participate - currently thinking of a few more contests to run (possibly perpetually).
For each of these, I could probably scrounge enough change out of my yearly shotgun shell funds to throw 20-$30 gift cards up for prizes
Photo Contest - This could be quarterly, I'd be interest in photo submissions that we could choose a winner each round and rotate through the background banner at the top of the site
Logo design contest - One time deal, but I feel we would have limited submissions so the payout would need to be higher.
Referral contests - I've done these in the past, they usually don't work that well but we have a more loyal member base here so I could be proven wrong. Biggest issue is tracking who referred who.
