West Alton River Rat and bobidan have it right; even the part about some A-Holes. :) There are some other important rules too. Try this link, but check back before going in 2013. There could be some changes. ALWAYS CHECK. That's the responsibility of all of us pullers. A puller wouldn't like it if MGPT surprised them, so a puller shouldn't show up with a surprise for MGPT and then get mad when MGPT says "NOT in this class."
