I'm not so sure that sending people to Hikingnaked.com (if that's the site you meant) is a good idea. The first thing a person sees there is Rule 1: You must be 18 or older to use the Hiking Naked Message Boards. No Exceptions! For your safety and the protection of young people, if you find anyone that is, or appears to be, younger than 18, contact the system administrator immediately. I can imagine someone who's new to naturism thinking "So this outdoor naturism business is for adults only, eh? Must be some pretty naughty stuff."
It's kind of a bugaboo of mine that we absolutely must not present naturism as being unfit for young people. Personally I won't participate on a website that excludes them--not that I expect large numbers to be interested! But I see it as very important. When I joined Freerangenaturism I posted an intro message saying I hadn't been in Secret Naturists, and I'm pretty sure (I knew of the place, but I can't entirely remember why I didn't join) that it was because they had an adults-only policy. Adults, you know, because it's all about "adult" topics.
