There are currently three publicly available mailing lists for Geronimo:
The user mailing list is for users of Geronimo to share their experiences and ask questions. Many of the developers monitor that list as well, to make sure questions don't go unanswered.
The developer mailing list is used by the developers to discuss plans, make decisions, vote on technical issues, etc. It also gets change notices whenever issues are added to or updated in JIRA. This list has a higher volume, though some conversations take place on IRC as well.
This list receives notifications (with diffs) every time a change is committed to the Geronimo source tree. It also receives change notices for changes to the Geronimo Wiki.
The Geronimo PMC has additional mailing list to resolve any administrative issues, personal issues, and security issues. Subscriptions to these lists are limited to Geronimo PMC members (and ASF Members):
