The occasional bit of "adult language" is fine but please don't go overboard. The Old 97’s don't fill their songs with swear words so why should you fill your posts with such words?
Also, any hateful language (racist, sexist, homophobic, etc. remarks) will not be tolerated. Posts containing these kinds of remarks will be edited or deleted by the mods and the poster will receive a warning. Rack up enough warnings and the poster will be banned from the boards.
