Is there potential in Adult sites?

Start reading gfy - which is the biggest adult webmaster forum.

Also check out some of the smaller forums. In this business, people do tend to help others, even more so in a smaller forum such as adultnetsuprise. At that particular site they have group projects that they work on every week and other group activites to help you along in site building and business building. It was very helpful for me to watch the entire group take some pics from a content provider, make a site, submit the site and make money and explain why they are doing what they were doing every step of the way.
