The period to submit proposals to teach a tutorial at PyCon 2010 US ends on Sunday, October 18th. There is still time for you to get a proposal on your favorite Python topic and teach a 3-hour class (with breaks and refreshments) to your colleagues on the Wednesday or Thursday before the conference ("Tutorial Days"). An example proposal (and a blank template) can be found at http://us.pycon.org/2010/tutorials/proposals/ . Thanks! Greg Lindstrom
