+ * _sipb-ec-people_: Is an archived version of _sipb-ec_ that is solely for emergencies and discussing sensitive issues when holding a closed EC meeting isn't otherwise possible.
+ * _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.
