Bugarup University. The Australian Discworld mailing list, at least that's what we call it, but we have plenty of honorary Fourecksians from around the Roundworld too. Not to mention the penguin, werewolf librarian, ex-pat Irish vampire, reluctant hobbit, woll, and probably some other species we've forgotten.
Rather than a list for the discussion of Discworld and Pratchett specifically, it's more a meeting place for general discussion of everything and anything, by people who have in common an enjoyment of the Discworld novels. The only real rules on content are try to post intelligently and remember to have some respect for other people.
Oh yeah, we have a thing that new posters have to be approved by a moderator - you can join and read whatever you like, but because of the spambots joining and posting, we need you to prove you are human (or at least sentient) before we let you loose on the university grounds, so join up, read a bit and when you are ready to post, send us a hello, and we'll process your enrolment as quickly as Hex will allow.
