Cannot subscribe through [email protected]

(Please CC me as I cannot seem to subscribe to the list.)

Hi,

I used to use gmane.emacs.gnus.general to monitor [email protected].
Recently I am trying to migrate to a pure email based workflow.  I tried
to send a mail to [email protected] to subscribe to the list, but I
cannot get any reply.  The same with [email protected].
If any admin is around, can you help take a look?  TIA!
