Way back when the internet was young (1980's), I had dial-up service with Genie (GE Information Network) on my Atari 1024ST. There was a game called Stellar Warrior there that was a real time ASCII space battle game. I started a squadron called Silver Swords (named after my guild in DnD). The hull designation on my ship was assigned SS6067. I have used it ever since for every game I've played.
