[Mailman-Users] Admin mail interface?

[Kyle Rhorer]

Forgive me if this has been discussed already, but I wonder about a mail 
interface for admin functions like approving subscription requests.  It 
would be really convenient if the list owner could simply reply with 
some incantation to the notice that there is a request pending.  Does 
this feature already exist?  I didn't see it mentioned in the listed 
features or in the feature request database.
