About bboards

Electronic bulletin boards (bboards) are a function of Cyrus email. They are electronic mailboxes that can be read or posted to by one or more people. 

Bboard Trees

Bboards are organized in a tree structure where each "tree" represents a bboard purpose. Below are descriptions of the top-level bulletin boards.

  • official -Restricted posting bboards that contain official information from various places.
  • academic -Course bboards.
  • cmu - Top level for campus-wide usenet groups, like, including bboards imported from the School of Computer Science (cs). Bboards under the cmu level may be distributed to other systems on campus under a special protocol (e.g., to CS, SEI, the Computer Club, PSC).  No new bboards can be created in the cmu tree at this time.
  • graffiti - In general, these are bboards for random, recreational scribbling. Bboards whose names target individuals for ridicule or offense will, at the individual's request, be removed.  These bboards are openly available to the university community for reading and posting messages.
  • assocs - Top-level for various associations, formal and informal, at Carnegie Mellon. These bboards are always available to the university community for reading and posting messages.
  • org - Bboards devoted to university departments.
  • internet- Mailing lists distributed across the Internet and other external networks are presented as bboards here.  No new lists will be created in the internet tree at this time, however Computing Services will continue to maintain existing subscriptions.
