This year I really, desperately want fic for one specific fandom. There are other fandoms I'm okay with requesting and I'd probably still enjoy my gift, but to be honest I would be rather disappointed NOT to get fic for the fandom I want most (especially since the fandom I want most is not the tiniest of tiny fandoms and there will probably be a handful of people offering to write for it).

So my question is: how do I heighten my chances of receiving fic for this particular fandom?
