Never learned it growing up.
I took a 'community enrichment course' last fall from a terp, but she kept vocalizing the words and then signing it. I couldn't hear most of the words, so I quit that class.
I'm learning on Lifeprint and trying to get over my nervousness to remember and use sign among other deafies during Deaf Night Outs.
I really want to take accredited ASL courses from a deaf teacher, but in my state, that is available only at an university 200 miles away. I'm thinking of moving there after I complete my 2-year. If I do, I'll definitely take the courses there.
