Good idea!

There are lots of predators around. You are already aware that you need to be a bit careful. Don't publicize the exact time and place but you can publicize it through local counselor's offices and/or other officials. You've already figured that out. The place could be anywhere where you have some privacy. Have all the attendees sign a non-disclosure statement that they will not share what they hear. I had some major problems with somebody doing that in the first group I was in.
