Welcome, RocketmanAA!
PartyPoker was the first site I played online poker on. But I found when I had PP on my coputer, I was bombarded with all kinds of gambling pop-ups, pop-unders, adware, you name it. It was hell finding it and getting it out. Since I got rid of PP, I've never ahd the same problems.
I like
PokerStars, and I've really come to enjoy
Titan. (Although I wish they'd quit with the pop up when you sign off.) One of the things I like about
Titan is you can see on the chat what your hand was when you folded. I sometimes check to see if I made the right decision to fold, or if the hand would have been good. The stats page is very cool, too. Very detailed.
