Hi,
I've recently launched a new directory at .
It's based on DMOZ, so there are categories for photographers, content producers, models, adult staffing, models sites etc etc
The links back are direct links, so as soon as the directory gets Google PR, it'll help out with your sites pagerank as well as traffic.
I'd like to invite anyone who wishes to to submit their sites. I recipricol link is not requested, though one is always a bonus!
