If your TA is not being helpful then you shouldn't use her. She should be there to answer your questions and help you out. My advice to you is to use Tammy (the host) as your TA. I am using her and so are a lot of the girls on this board and I can personally tell you that she is AMAZING! She is really helpful, gets back to you quickly, and offers advice w/o pushing you into doing something you don't want to do.
