I know this is a bit of a longshot (no OoT reference intended), but maybe do a half-join with another zelda website?
There are loads of Zelda websites, Zeld aWorld, Zelda Universe, Legends and Adventures... Im sure lots of the people who post fan art and fan fic on there would be intreseted in ZFGC and it might inspire some people to try and make their own games.
I used to just visit Legends and Adventures and read the Fan Fic, then I haerd about OoT2d somewhere, and by then had fallen in love with the world of Hyrule.
But seeing as they're seperate websites I see how this could be impossible.
