>>3 I haven't myself talked with the school counslers about this idea, but I believe my parents and therapist have. Personally, at my school has clubs during lunch hour along with the before and after school hours. I've actually started another club or group last year, but didn't last long because of the lack of members.
I get where you're going for the gang part, here's the thing... since most if not all schools don't allow any symbolism of gangs, like scarves or bandanas, but the DOLLARS don't have any symbol of that, instead a name or a logo. If we can convince the people that the DOLLARS aren't your usual "gang" we might able to put the DOLLARS more out there.
