I am making an unofficial announcement here that it looks like we will be able to go with Roundup as the issue tracker for python-dev. Now this does not mean people should stop volunteering by emailing infrastructure at python.org! We have not finalized which of the volunteers will be asked to help admin the Roundup installation so if you want to help please email us with your timezone, rough amount of time you can donate per week, and your Roundup experience.
This announcement is unofficial because there has been an offer for professional Roundup hosting. We are awaiting the details of the offer before deciding how to proceed. Once we have decided how we are going to handling hosting there will be an official announcement with more details.
