[Nathan, please don't send only to me: make sure you're using "Reply to
All" and that tutor@python.org is also being replied to. I'm actually
going slightly crazy with work right now, but there are other people on
the mailing list who can help.
I'm forwarding your message to the rest of the mailing list now. Good
luck!]
