I know this is an older topic, but more people are posting to Archive of Our Own (AO3) these days.
Also, to let everyone know, I nominated Gatchaman as one of the fandoms for Yuletide again this year. Sign-ups happen Oct 19-25 with fics due by Dec 20. You have to request 3-6 fandoms and your writer only has to write one fandom gift, so there is no guarantee that Gatchaman will be chosen. But if more of us sign up, request, and offer this fandom, the better our chances of getting something written. If you need more info, the FAQ for Yuletide is here:
