Seems an apt date to realise that I didn't say much :( Assuming that I'm correct would you like an issue raised on the bug tracker? If not please correct the mistake I've made, presumably in reading the docs, which I think are excellent by the way. -- If you're using GoogleCrap™ please read this http://wiki.python.org/moin/GoogleGroupsPython.
