All have been tested and a lot of research was done to find the best ones nowadays. I probably missed a few as those were the ones off the top of my head.

Again..best of luck with your hunt as I actually don't know of many of where you can submit paysites. That is what you're referring to correct?

Would this be for your own FHGs etc? Sponsor Hosted Blogs as well? I try to hit up affiliates who have link lists and a lot of times they will list your Hosted Blog. Don't know if that helps at all. Hope so.
