I had so much fun last month reccing away for my category - I had to restrain myself from posting too many :P I've got the reccing bug...

I really like the category system as it is - seeing as Category: Other, allows for some of the more obscure pairings/genres.

I'll suggest a Friendship: Team category, cos there's a lot of great fics out there that explore that dynamic (but it might be a bit close to Genre: Gen, which is already there on it's own) :D
