Here's the thing, B A is not for real money in other words, your not playing to win or loose money through the site. I have become to busy for poker now, but I miss the community, they are very welcoming to new players. I spent a lot of last year on B A, rising up the ranks and I have a lot of really great memories from the experience. B A has a really great community with Texes Holdem poker tournaments, plus cash and sit and go games all the time, as well as weekly tournaments in other games. You can play for free for the first month and then I believe it is round 10 dollars a month after that. It has windows clients for holdem and draw poker, hearts, crevege and one more that I'm forgetting at the moment. However, try out Blind adrenaline, as the name implies, is a gaming platform for blind people.
Most, if not all of the main stream online gambling sites are not accessible.
