I know some. I can hold a basic conversation and talk about school-related things (right now I'm doing an internship at a school for the deaf).
Excellent free website for teaching yourself ASL:
http://www.lifeprint.com/index.htmIt's organized into short, practical themed lessons with vocabulary and practice sentences and dialogues. The site's dictionary is kind of small and there aren't videos for everything ('cause it's one guy with a day job running the site off donations). But you can search "asl dictionary" and find all kinds of those.
