This is very interesting POV. I see your point with mirroring Free sites. They could be seen as redundant for SE's. One the other hand there are galleries that I submit to TGP's . I have a partner account with Elephant list. They do not accept other site recips on the gallery. so I have no choice but to mirror the site to get listed to other TGP's. Do I make 30 different galleries every day? I have changed my freesite submit list so I do not mirror them any more. So we will see how that works.On Freesites I'll submit only index.html
Thanks Lowry
