I very much like the idea of a big site totally devoted to FM stories - a place to get all the new stuff, plus a huge backlog of old stuff too. The only question is, what about illustrations? Would they be supported?
Yes, illustrations would be supported. Authors would be able to upload images and then embed them as illustrations in stories. The image would appear about 250px wide in the story (subject to my site design) and would be clickable to a larger version if the creator had uploaded one. Eventually we would support comics.
I'm trying to figure out the scope of the thing. Is it just FMG? Is it just femuscle? Is it just growth? My inclination is to go wide - to make it an archive committed to all stories where the feminine is the powerful. So that would be Xena fan fiction, FMG, arm wrestling stories, giantess, superheroines, whatever. Just open it up to everybody, and have sections for both the erotic and non-erotic.
This would also open up the opportunity for content creators to sell their work, though I wouldn't launch the store until the site had a large amount of free content.
