We were using the mailman2 instance provided by Dreamhost for many years as the mailing list for dgplug. But, over the years many participants had trouble with receiving emails. In the last few years, most emails were landing in spam.
So, we took the chance to move to a new mailing list, and also started working on the site to have CoC properly defined. To make things easier, we will just follow the PSF Code of conduct https://www.python.org/psf/conduct/, most of our members are already parts of various upstream communities. So, this will be nothing new for them. We will be also updating our sites to add details of a separate team who will handle CoC violation reports.
Summer Training will start from 25th July, so remember to join in the new mailing list before that. See you all on IRC #dgplug channel on Libera server.
