Up until now, it's been fairly tricky to set up an account on the Python Community Server. I finally got around to following the howto and building an installer that will make it all easy. Here it is:
Radio UserLand installer for PyCS
Download and run that and you should be up and running straight away with a blog on pycs.net. You'll have a numeric URL (something along the lines of pycs.net/users/1234567) at first, but drop me a line and I can symlink you a more reasonable one.
