I am deaf, i just looked http://www.handspeak.com/ online, this might help you out some. or what bobbi just said (the one with the star), suggesting - go to the library check out an ASL sign lang book, those might help you, they have pictures and good defention of how-to-do. Or, find a deaf vedio (i have one - had it when i was a kid) little story movie, short ones, and they sign through the entire thing, however, there is voices to tell you what they are saying. perhaps check that out? my vedio mus be at lest 20 some years old, it had the 3 little bears, and the pig story.
you could study online, you could take some classes, books. there are many ways, better yet, if you have a IRL friend that knows sign language. online most likly will not teach you the bad words. not that i know of, maybe try youtube.com?
