All you need is at least 4 members, a name and some sort of goal/code/agenda and a motto to sign your posts with. I am currently tossing around a few ideas for mine (something to do with functional programming) but feel free to discuss.
Faction: The Poor Fellow-Soldiers of Cudder and of the Temple of /prog/, commonly known as the Knights of /prog/, the Order of /prog/ or simply as /prog/riders.
Agenda: TKOP provide high quality server/client solutions to the masses of /prog/ in an effort to deal with the ever increasing shitstorm.
Some of the things we have released include: userscripts, /prog/scrapers, anonymous chatservers, "safe enough" encryption methods, distributed anonymous BBSs, etc...
