I run a couple of "mom and pop" goth sites, and am finally starting to get my referral program into shape... We pay (generally) 50% including recurring. I work closely with people (who want it) to help them promote the site, including providing content and so-forth.
For more info, check out
http://www.gothicamateur.com/referral.html or hit me up in ICQ 155863658. This is the same program as my other site, Blood Dolls, which someone else mentioned above. (Thanks!) The programs are linked, as are the sites, so you get two chances for people to convert.
The best thing to do is to send people to Blood Dolls. It has a more general appeal... That will send them to GothicAmateur.com. That actually converts goth traffic better, currently. Then, if they don't sign up, they get a trial offer which has been snagging a lot of people.
