[Mailman-Users] How to configure a list for invitation-only subscriptions?

[Carter Braxton]

How can I configure an existing mailing list to be invitation-only? (That is, disabling the ability for the general public to sign up via the web or email interfaces unless an invitation is received first.) I must be missing something as I'm sure this is a very common requirement, but have not seen anything obvious in the list's options, mailman docs, or google searches. Thanks for help with this!
