On another note, I really think that loyalty bonuses should NOT come from the affiliates pocket, and should NOT in any way affect aff. commission for the simple fact that if a caisno gives $100 on the 31st to 1,000 of my players – I sure would be left with nothing 
Sure, they’ll loose them, but when they do I will not gain anything and a casino could do this all the time (I am pretty sure that there was a group of casinos doing this at one time).
The minute I saw my poker commission negative – I switched over to CPA. I think it makes no sence to be negative when you get paid by a hand played…Not a big poker advertiser, though, so it works fine with me. I would much rather get $3-$4K a month than $60-$70…
