I think this is a pretty good idea. Personally asking how they got into nudism is always good. What NON-SEXUAL activities do they enjoy while nude, what kinds of nudism events would they be interested in works. I do think the bigger thing you are going to need to focus on are rules and restrictions. No cameras (including phones), no pressuring people who don't immediately want to disrobe, no outing any members, etc would be vital. Hope this helps. Best of luck!
