Until Feb. 2013, there was a VPython mailing list whose archives may be found at https://sourceforge.net/mailarchive/forum.php?forum_name=visualpython-users. Please do not write to that list; instead post on the VPython 7 or Web VPython user forum.
VPython on Stackoverflow: A third party question and answer site for users to share about VPython. We encourage people to post to the VPython user forum or the Web VPython user forum rather than to Stackoverflow, as there is a large number of knowledgeable users in these forums and one will get a faster response.
