* _bug-sipb_: Bug reports about the SIPB locker. Please add yourself if you're maintaining the locker.
* _sipb-machine-room_: Discussion of SMR-related issues. Feel free to add yourself.
* _sipb-machine-room-access_: Reflects who has card access to SMR. Maintained by the Vice-Chair. Generally, email before granting card access to give people a chance to object before you do so.
+ * _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.
