Dear Qubes Community,
Due to excessive spam, we have changed the posting policy for our mailing lists. All mailing lists now require users to subscribe before they'll be able to post. (A Google account is still *not* required to subscribe or post to any of our mailing lists; see below.)
Since the qubes-devel list has already had this policy for a long time, no changes have been made to the way qubes-devel behaves. Rather, this change simply brings all the other mailing lists (qubes-users, qubes-project, and qubes-translation) in line with qubes-devel's existing behavior.
For information about how to subscribe and post to the mailing lists, please see: Help, support, mailing lists, and forum | Qubes OS
Please note: There is a common misconception that a Google account is required to interact with the Qubes mailing lists. This is not true. Many people simply assume that a Google account is required when they see "@googlegroups.com" or try to interact with the Google Groups web interface. A Google email address is not required. Any email address will do. The Google Groups web interface is also not required for viewing these mailing lists on the web, as there are traditional mail archives you can use instead. (See the page linked above for links and further details.)
