The rules for using language in Aetolia are simple. Do not inflict obscene language on people who you do not _know_ are willing to hear it, and do not use racist or homophobic language at all. We don't care what you talk about in tells with friends, but we do not want to see offensive language on any public channels, city channels, or guild channels. The head of a clan may dictate what sort of language he or she wishes to allow in his or her clan.
