Community -- the community around GNU Hurd.

Trackers -- for reporting issues.

Mailing Lists -- preferred for general discussions, questions, bug reports, etc.

IRC -- for interactive discussions with a smaller audience.

Non-public mail contact to the maintainers.

If you have a concern you want to send to the Hurd maintainers without writing to a public mailing list, then please send email to [email protected]. Please don't send general support requests or questions there, but instead use the mailing lists.
