Feedback from our members...
I have been a member of AdultFolio from the start. I find I get more work through this site than the others as they allow people to see exactly what you do and not just cover it with the term Adult.
I've been using Adult Folio for a few years and find it to be a great place to arrange shoots through.
The site is well administered and any issues are dealt with professionally and swiftly.
It's easy to navigate and contact people through, with a good level of security for all users.
