I converted one of my hubs into a thumbnailed TGP.
3D Porn Galaxy.
It requires a 150x200 thumb, and if you want to submit free sites to it, feel free, just make sure you add a thumb as it is a requirement.
sorry for the not the same size as the link lists, but since it is just thumbnails 88x88 would be way too small.
Right now, there is no limit on submissions, so
submit away. You can also
apply for a partner status. If I know you from here, I'll enable you to submit recip free links if you have stuff you want to back submit.
I don't know if any of you are doing 3D Porn, but wanted to put the word out.
