I'm all about tagging - once this site gets big, it's going to be awesome to be able to say "give me all the questions related to the particle と".
I've started tagging particle questions accordingly: particle-to, particle-ni, etc.
I wanted to just put "to" in romaji, but the StackExchange engine wouldn't let me (probably because it's the English "to"). Is there a way around this? Or do people agree with my "prefixing" of the word particle?
