We're not quite settled on the wordcount, I'm thinking 25k, unless anyone has strenuous objections.
Basically anything you like that has Steve and Tony as prominent characters, but it can't be focused on a ship that's Steve/other or Tony/other. Theoretically, if you wrote a Jan/Sam story with lots of Tony and Steve being their supportive friends and trying to matchmake but never being romantically interested in each other, that would also be okay to post on the comm - we actually have laxer rules than you'd think from the fic we have. (Which is fine by me as I love Steve/Tony, but we do allow some other things!)
So yeah, non-canon verses, crossovers, fusions, fic where Tony travels through reality nailing all the Steves he can find, fic where Tony's a hurricane and Steve's the sea and they make beautiful waves together. Anything you like - although do bear in mind you probably want to write something that will appeal to an artist and give them ideas.
