 - "Be excellent to each other" is the overriding principle of Protospace.

 - Don’t be easily annoyed, don’t be excessively annoying
-- Protospace specific units of measure:
-- Toast: unit of volume, weight, distance, equal to a single slice of standard toast
-- Damron Factor: an increment of 7 powerbars and extension cords connected to each other

 	- Protospace has 10 designated parking spots in the rear parking lot, and none in the front parking lot. Refer to the map to see their locations. It is important that we do not abuse the parking lot assignments by parking in spaces that do not belong to Protospace. This is especially important where spots belonging to GT Auto are concerned, as this has been a source of conflict in the past.
 	- If you are unsure of where to park in the parking lot, there is plenty of legal street parking on the roads adjacent to the industrial complex.
