Hi
I am a newbie as far as poker is concerned, but I have played (small-time) at on-line casinos for years..... Not that that makes me an expert!
One of the biggest problems is finding a Casino group or stand-alone Casino who offers realistic bonuses and who has the reputation of paying when you win.
I have played at some of the worst (20/20 hind-sight) Casinos on the net, but have found that there are 1 or 2 "watch-dog" sites that offer accredited status to those casinos who are consistent in their interpretation of their T&C, pay in a timely manner, handle customer questions promptly & honestly.
Given the number of "Rogue" Casinos that are operating now, I would suggest that you Google for accredited Casinos that have been recommended by reputable watchdog sites.
If I can help any further, please feel free to PM me.
Cheers
Joe
