Glad to have you around.
As far as I know poker has changed massively since you've been away from the game. 100nl definitely isn't the same any more, everyone has improved. Since BF Pokerstars
has become a lot softer so you can try there, it's the biggest and no Americans that actually know how to play poker are there any more.
There's a Skype group where some serious discussion goes on, I'm not in it any more because I can't seem to get Skype working on my laptop lol. I'm sure someone will pop in and pm you soon, if not, post in the chat thread and you'll get a reply about it.
Stick around, start some threads and pop over to the Hand Analysis section. We can always use more people talking about the game. Good luck.
