First, there's a Jython sprint being held in San Francisco on Saturday, February 16th. The sprinters are concentrating on tasks for Jython 2.5, following the newly updated Jython road map.
A week later on Saturday February 23rd, we're holding an online Python Bug Day. Participants will meet in the #python-dev channel on IRC, and look at open bugs and patches in Python's bug tracker. Last month's bug day closed 37 issues; will we do even better this month?
