I think we had something like that here, about.. three years ago. Or four. Barbara Gordon had organized it from what I remember of those days. Practice teams, with magic, supers, fighters, paranormal, etc. getting together with training drills, test runs, mock battles, things like that. And rooftop tag but I don't recall being involved in that part of it
Would be nice to have something like that again. The classes are great but yours and the Captain's idea is a great one as far as I can tell. I fully support this. I've never taught before but I could maybe be an assistant trainer to start with (like help the main teacher, help set equipment up or whatever). But training.. yes, I'd really be open to the training and practice aspect.
