In an ideal world it should be a good idea. In an ideal world more women would feel comfortable with naturism. In an ideal world naturism would just be a part of everyones lives. All we can do is find ways to tweak our world towards the ideal.

no chance of that happening!
Too many barriers, too much religion, too many "moralists"!...
People prefer to "follow" the ways traced by others than to seek their own way of thinking.

I think a "dating service" is beyond the scope of ANW, no matter how good the intentions are. And the reason I see it as unfit is because it's already on the way of becoming one: the more safe it appears, particularly to single woman, who may posting about their daily naturist life, the more chances anyone can approach her directly and perhaps develop a relationship in "real life", if they fancy each other. If beaches or ANW become more like "let me try to openly display I'm looking", it will end up being misused. I see no problem approaching anyone here, start to have nice conversations with them, and then following it up with whatever they see fit. But approaching someone simply because you've seen him or her naked sound a bit like "naked people are easy".

I wouldn't want to have to wear a symbol to display unavailibilty, and would certainly be offended if my wife had to wear one to go to a nude beach by herself. I have no problems with anyone approaching her in a decent matter, like people do in clothed contexts, but wearing something to assert that she is not interested in more direct approaches comes as offensive. Last year, we met a single guy at a nude beach. He was asking for directions and we found out we have stuff in common, like the country of origin (it was in another country). It's possible to be a single man, approach people, and yet don't appear like a creep.

I wasn't expecting any "miracle" solution by posting my message here, I just wanted to share a subject that touches me and that I regret.

Wouldn't it be nice if there was a miracle solution. It is good for us to consider and chat about ideas and options and issues though.
