The frontpage of the [
http://trac.common-lisp.net/clo/wiki/WikiStart Trac wiki for the project] lists a clo-announce mailing list. While I don't see much value in having an announcements list for the project itself, I do see value in having a (limited posters only!) mailing list to do announcements regarding the site, like maintenance, changes, etc.
Is this a good or a bad idea? (Who doesn't want these updates can simply decide not to subscribe...)
