They are a network of blogs on wordpress. However the main anchor site I have built it up with pages and everything so it's a full site. I have galleries, cartoon pages, crossdresser story pages (that's the niche, crossdressers, sissies and transsexuals), a store and so on.
I make my money off pushing niche paysite sponsors, dating services and webcams. I even sell ad space. I push around 4 dozen different paysites, dating, cam and PPV sites.
All you have to do now is update the post, the rest takes care of itself. If anyone bought it I'd switch all the affiliate links, you'd just have to sign up to all of them.
I can make a months worth of post for all of them in about 3 days, I update each one every 3 days, my main one every other day. Anyone interested email or PM me please.
BTW my main site in in my sig.
