Entries are free of charge. The initial joining requires a reply to an e-mail. I had problems getting their initial profile form to function, and gave up. There will be a newsletter sent out to all subscribers, something not mentioned until you receive your confirmation e-mail, which you may unsubscribe from. The site is difficult to negotiate initially, needing four or five screens before you find the first profile, although there do appear to be a healthy range of profiles available when you finally get there.
Entries are presently free of charge.
Send a brief description along with the URL of the web site and I will check it out.
