There are several mailing lists for zsh:
The shell is being maintained by various (entirely self-appointed) subscribers to the mailing list,
zsh-workers@math.gatech.edu
so mail on any issues (bug reports, suggestions, complaints...) related to the development of the shell should be sent there. If you want someone to mail you directly, say so. Most patches to zsh appear there first.
Please note when reporting bugs that many exist only on certain architectures, which the developers may not have access to. In this case debugging information, as detailed as possible, is particularly welcome.
Two progressively lower volume lists exist, one with messages concerning the use of zsh,
zsh-users@math.gatech.edu
and one just containing announcements: about releases, about major changes in the shell, or this FAQ, for example,
zsh-announce@math.gatech.edu
(posting to the last one is currently restricted).
Note that you should only join one of these lists: people on zsh-workers receive all the lists, and people on zsh-users will also receive the announcements list.
The lists are handled by an automated server. The instructions for zsh-announce and zsh-users are the same as for zsh-workers: just change zsh-workers to whatever in the following.
To join zsh-workers, send email to
zsh-workers-request@math.gatech.edu
with the subject line (this is a change from the old list)
subscribe <your-email-address>
e.g.
Subject: subscribe P.Stephenson@swansea.ac.uk
and you can unsubscribe in the same way. The list maintainer, Richard Coleman, can be reached at coleman@math.gatech.edu.
