When setting up mailman lists, here's some settings to use:

• General
  • description and info: something explaining the purpose of the list
  • consider "Should administrator get notices of subscribes and unsubscribes?" (admin_notify_mchanges)
• Password
  • consider using Passwords
• Non-digest options
  • Consider setting a footer: for example, tape groups probably want a link to the signup spreadsheet in the footer
• Digest options
  • Conceivably we could disable digests? Digests seem dumb to me, but hopefully nobody turns them on accidentally
  • You could set the footer here too?
• Privacy options
  • Subscription rules
    
    • Consider requiring approval to sign up
    • Consider making list membership admin only?
  • Sender filters
    • Consider defaulting new members to moderated
• Archiving options
  • public archives might make sense?
  • yearly or quarterly archives may be better than monthly
