How does a group change moderators?
Ideally, the old moderator or team hands off control of the group to the new moderator(s) by sending an e-mail to email@example.com. Up-to-date contact addresses for the moderator(s) should be supplied in that e-mail at the same time that the request is made.
As a courtesy but as not a requirement, the outgoing moderator might inform the Big-8 Management Board about the change in moderators. It is the ISC, not the Board, that maintains the official list of submission addresses used by the moderation system.
If the original moderation scheme seems to be broken, interested parties may initiate a Moderator Vacancy Investigation.
