I appreciate this question.
I can only speak for myself, but I am not allowed yet. I can look, but cannot touch. I am sure that we have many voyeurs of different ilks out there who have little to offer. Translation -- sign me up, and let me spend my time sucking up some soft core if I can find it.
Which brings me to a question. Why can people look, but not post, to G&N for a time? Someone told me that it was to eliminate juvenile behavior, but that is easily done with a perma-ban. I am a guest here, so I respect the rules, but I wonder.... If you can gaze all you want, why participate? More importantly, why prove you CAN participate?
Would it make more sense to separate glamor and nude? Glamor deserves its own space -- its one of the toughest and widest-ranging specialties out there. Then nudes could be CLOSED to all folks until they invest their time in the forum.
I bet participation would go up, since the newer blood is often the more enthusiastic blood.
Just a thought.
