Dylan,
There was a great show-offs website that will soon be back up again. The webmaster became a friend of ours a while back. His original partner died suddenly earlier this year, and her kids ended up screwing Bryan out of the website (well the domain name actually). He'll soon have the website back up again at
http://www.asocommunity.com/
He has a member base of close to 50,000, with quite a few being really active. ASO stands for "Adult Show Offs" and it was developed a couple of years ago from the Yahoo Group of the same name. It should be back up and running by the end of next week. Have a look, it is the best of it's type.
