We have set the mailman-developers list to moderate all new users because of a recent problem with some people subscribing to this list and then posting messages that belong elsewhere, often messages that belong on mailman-users instead.

Note that this list is closed to postings from non-subscribers. You must first subscribe and confirm, then you can post to the list.

Also note that all posts made to the list will be publicly archived.

In order to protect the integrity of the list archives, we do not routinely agree to remove or obscure posts that are in the archives. We only do this in exceptional circumstances such as if someone has posted personal/private information about someone else, or an obviously private e-mail has accidentally been posted to the list.
