Yiddish Alphabet - by Goatling - Memrise created by Goatling

Found a page where I’m asked to choose the letter s(of) and it appears twice. Anyone know if this person is still active and can address the issue? I know a beginner Yiddish class that’s just starting up and this would be a great resource. It would be a shame to have this problem persist. Is there a better way to communicate errors with the developers of community-created lessons? I’ve found problems in other courses as well. Thanks
