The various Zope developer communities use several IRC channels for communication:
This channel serves the Zope2, Zope3, and ZTK developers. These developers hold a weekly half-hour meeting in the channel on Tuesdays from 15:00 - 15:30 UTC.
Logs for the channel are available: http://zope3.pov.lt/irclogs-zope/
This channel serves the Zope3 and ZTK developers. Some people prefer it over #zope since it’s free of legacy Zope2 issues that sometimes muddle things up.

This channel serves the Grok developers.
