I think every project which has mailing list on common-lisp.net has on the project page a link to http://common-lisp.net/cgi-bin/mailman/listinfo/%7Blist-name%7D.
Today all these links form all project pages are broken.
For those who unaware about the listinfo page. It allowed, for project owner to: - change list options - see the mailing list subscribers - maybe something else I don't remember
For users it allsows to: - subscribe - unsubscribe - change subscriptions options (e.g. receive every email, receive a digest, do not receive emails; and other options).
Also this page linkns to the mailing list archives.
I think this functionality should be restored.
Best regards, - Anton
