i would say a fake tgp of a hub for all the pages you make and all the sponsors you use for the freesites/galleries and so on you make....

The main index of your domain is a good place for a site like a hub page...
and use folders (not subdomains) for your freesites...

But in a newbie myself in this, so take what i say with a lil salt and hope someone thats been in adult a bit longer can answer you better...
