I think WSOP did a great job with their software, I can play on my Mac and PC. I can resize the tables, choose which seat I want to be in, etc. No complaints at all about the software. The games are pretty good too, although a little light in the number of players sometimes, depending on the time of day. It would be great if they did a better job about syncing their player points with Total Rewards...unless they do and I don't know about it.
Every time I sign in, it tells me that I'm not in Nevada, so I have to close the software, turn off LTE on my iphone, and then restart the software, and it works fine.
Only thing that would have made this better is if I got a sign up bonus from Poker Atlas like you are offering for Party. Can someone have Jon or Jackie hook me up? ;)
