Perhaps the categories should be parsed down to something more manageable. Suggestion: nix the genre categories...and just have people use those when they tag other fics. How many fics are produced in some of the rarer pairs? If there's not much, that might explain why there's not so many reccers. Instead, there could just be a blanket "rarepair" category instead. If you need help with the behind-the-scenes stuff, I could help you.
