Hey there,
I checked the FAQ for this but didn't see anything, so I figured that I may as well post it here...
Perhaps it would be a good idea to put any possible rules about languages on the forum in the FAQ. While I don't have any problems with people having conversations in Japanese or French or whatever, others may, and I've seen various IRC channels and boards with English-only rules.
As far as other languages go...profanity filters are annoying, but perhaps a PG-13 rating for the forum would be a nice thing to have at times...
