I did my Yuletide sign-up today. I only offered seven fandoms. There are others I'm familiar with, but only seven where I really felt I could review canon and write well. (I never offer the fandoms I'm requesting. I don't have a good reason for that at all but it has become my tradition somehow.) But really offering a large number doesn't help them match you so much as far as I know, and several of my offered fandoms have already been requested by people, so I should be OK.
So far it doesn't look like anyone is interested in requesting (or writing) Les Revenants though. That surprises me.
