Gabsclan began as another list called the Clan MacGab, which was divided into several regiments including the Royal Highland GabWhackers, the ROCswatters, the Potedaian Posse and the regiment I belonged to, the Royal GABernacle Choir. We inhabited a virtual city called Gabardeen, which has establishments like the Kit Kat Klub and the Staff and Bard.
Organizational changes and a subsequent rift divided the Clan MacGab into two lists. The Clan MacGab moved off to form its own list, while those remaining retained the name Gabsclan. The Gabsclan list stayed on its original server at the University of Texas for a while and was then moved to a new server in Indiana.
Despite the split, we retain a vocabulary all our own, which we call Gabberish. It includes terms like "gabwhacker" for Gabrielle's staff and "merkin" for the little bit of white fluff at one end of it.
I doubt the Gabsclan web page really does the list justice. To really get a feel for our wackiness, you pretty well have to experience it for yourself.
