This is the course form for the course in the ISL alphabet https://www.memrise.com/course/1539697/irish-sign-language-alphabet/
Questions, corrections and offers of help appreciated. It would be great to have photos of the hand gestures as well. I am going to email some of the people who have made apps and websites to help people with ISL and see if they’d be interested in making their own memrise courses or letting me have a few resources to make a course with basic phrases.
