Discussion Groups

• Email is typically 1-to-1
• Aliases/Distribution Lists allows 1-to-many
• Mailing Lists (majordomo)
  • Examples- TBTF, Scout Report
  • Users can join, leave by email (automated also)
• Newsgroups (aka BBS) better mechanism than mailing lists when number of users is reasonably big.
• Newsgroups are not delivered to each user. It is a common system area which users can read.
