In recent commits we changed from auto-inviting all users to all new
puzzle channels to instead notify the main hunt channel whenever a new
puzzle channel becomes available.
Opt-out of channel invitations
------------------------------
-• Drop the auto-invitation of all hunt members to every new channel.
-
-• Announce all newly-created puzzles in the main hunt channel, (so
- that hunt members can easily click to join).
-
• Consider adding a user option to allow a user to opt-in to auto
invitation for all newly-created puzzle channels
