Are you sure they weren't asking for donations? I think theres special stuff for paid donors, but I didn't notice that it was a requirement. I mean, not that I could see.
I looked at the CHADD site for a meeting group in my area and the closest one is on the other side of town in the next city & mostly has children meetings. I wish they had one in my tiny part of Ft Lauderdale.I went to their site but it made me mad that they require membership payment.
