Can someone give me a Free Sites 101? I've never done them, I've only ever done AVS and TGPs.

I know every link list is going to have it's own quirks, but essentially what is required?

Does the free site have to be multiple pages or can it be one page?

Do they all require 20-30 pictures?

Are there certain large pic size requirements?

Are there maximum recip requirements?

Do they do better than TGPs or it's just more of the same?

Thanks
Michael
