We have been waiting for a sensing system to be programmed for security in CCL and sudo room.
Meanwhile, there have been incidents in and around the Omni that raise security concerns.
Starting in August we will start closing and locking the entry door.
If someone is having a workshop and wants to keep an open door for the duration, that's cool, prop it open.
When you exit the area please close the door and check that it locked.  
Here's how to unlock the door:
1. check to see no one is watching you
2. press the lever/switch on the box to the left of the door
(see photo) while saying "open sesame"
3. push open the door and enter.

to lock the door, just close it.
The door also opens from inside.
This message is coming to you via Sudo-discuss or CCL members at google groups.  Please pass it on to anyone who needs to know the procedure.
