Good American Sign Language Learning Assistance Sites?

Ok tomarrow I start an ASL class at my college and I was hoping to get some more sites to help my learning and retention of the language. I all ready know about http://asl.ms/ http://www.lifeprint.com/asl101/fingerspelling/fingerspelling.htm http://www.lifeprint.com/asl101/lessons/lesson01.htm Do the good people of Yahoo Answers have any more good sites? .

Does anybody know of any good sites where I could learn two handed sign language/?

My great-aunt is coming to visit us and she’s deaf but nobody in my family knows sign language. We don’t want her to feel ignored so we figured we should at least learn the basics. Is it hard to learn and how long should it take? Thanks! .
