Excellent share!
I took some paid courses a few years ago, but very little of it stuck. All I managed to achieve was the ASL equivalent of "vacation Spanish". Definitely going to sign up and give it another shot.
Edit: For context, I'm currently watching Echo, and some of the ASL isn't subtitled. I can interpret the gist of it, but not as much as I would like. I was just thinking yesterday that I needed to brush up.
