One word post, multiple one word posts, simple "I agree" posts, creating new threads that ask questions that have already been answered in the FAQ, posting in topics that are over a month old, discussing your broom, your lack thereof, the arrival of your new broom, the impending arrival of a new broom, etc., etc… is all considered SPAM, but is by no means an exclusive list. If you're not contributing anything to the discussion, don't post! You may lose points for it. At the very least, you risk irking your fellow schoolmates and professors. Remember that the boards will soon be managing 3000 registered students.
