Finally we have a mailing list: build-brigade@gnome.org. However, I am not able to post anything to it. I always get this error:
build-brigade@gnome.org
SMTP error from remote mailer after RCPT TO:<build-brigade@gnome.org>:
host mail.gnome.org [209.132.176.177]: 550 <build-brigade@gnome.org>:
User unknown in local recipient table
I guess I should contact Thomas Vander Stichele about this issue.
