Sempersystem

Sempersystem: A system where all or most headmates are always close to the front, but not always fully there. They may pop in to say a few words. Due to them always being in the front, it's easier to switch to a certain headmate. Sempersystems will most likely share all memories with each other, but may not.

Flags
The sempersystem flag was created by TheInvertedSystem after the coining.
