I think this is a great idea.
Although I've been kicking around the mental health system where I live for over 20 years, I still don't have anything in the way of an actual diagnosis. So I don't feel as though I can legitimately claim to be a "member" of any of the forums in the "Mental Health Support" listing in the main menu (e.g. Depression, Bipolar, Anxiety, Panic & Phobias, etc.) I do have at least a tenuous connection to the LGBTQ+ forum. (It's in the T.) But that forum sees very little activity in general (especially the T part.)
So, anyway, I think having a place for us mental health misfits to check in would be nice if there were to be sufficient interest. I can't say how active I'd be. I mostly just greet new members &, periodically, reply to threads in the Games forum. But it seems it would be a comfort to know such a place as you offer was here. So thanks for this.
I hope it becomes a great success!
