Starting with the Gremlin's code, Peter added many features including networking. For several years, almost all Seattle area Citadels ran this program. When Peter started to release source code, many offshoots were born.
There were two main source releases: 3.11 and 3.12. Most offshoots were derived from 3.11 code. However, Gremlin's Citadel, Captain's Citadel, and Maven's Citadel were derived from 3.12. TurboCit was derived from an earlier version of the source.
