I did give ~3 BTC to the ~10 beta test members before the BTCTalk launch. I guess I could give a few more coins out to the first few users with 200+ posts...
How'bout this? I'll give the first 10 people interested 0.1 BTC each (requirement: genuine interest, 200+ posts) - time limited offer.
Their withdrawals will be disabled until they msg me to check their total wager and if they've spent the coins on games, I'll re-enable withdrawals and they can keep any payouts.
