- * _sipb-ec_: reflects the current members of the EC, plus [an archive visible to all SIPB members](https://diswww.mit.edu/charon/sipb-ec/). There is no unarchived list; [this is intentional](https://diswww.mit.edu/charon/sipb-ec/4959) to add an extra barrier to private discussions, in order to discourage them.

+ * _sipb-ec-people_: Is a non-archived version of _sipb-ec_ that is solely for emergencies and for use by the EC for discussing sensitive issues.
+ * _sipb-discussion_: general discussion list. Generally little-used, but a decent place to move contentious discussions to from sipb-office if they continue for a long time. Members should feel free to add themselves. Prospectives should ask a member to be added.
