First of all, I want to say thank you. i have been trolling this forum for about 3 months now, and have learned a tremendous amount from all. While I still have some fishy tendencies, I am trying to get better, thus my request for help.

I have seen a couple of discussions on Poker Tracker. Is this the program to use? Do you use it, or have it open while you are playing and keep refreshing it?

I see may acronyms like VP$IP. What do these mean? What should I be trying to get them to as far as %'s? I appreciate any help I can get.
Thanks
