Since we use existing free open-source games as components, anyone interested in setting up such groups through the Crossfire-RPG interface can refer to that game's docs for details or play an existing Crossfire-RPG server to actually try it out or even set up a Crossfire-RPG server of their own to really dive into the nitty-gritty details.
However on the Milieu's "CrossCiv" server the code that in standard Crossfire-RPG distributions implements guilds or clans or whatever they call them of which each character can only be a member of one, has been cloned and name-changed so that in the CrossCiv-server each character can be a member of only one clan and also a member of only one guild and also a member of only one society and also a member of only one association and also a member of only one "party" (as in democratic party, republican party, anarchist party and so on).
In the CoffeeMUD interface CoffeeMUD by default comes with a whole bunch of types of clan, including family, fellowship, guild, gang and so on, with various governance details such as a gang has one leader who has all powers and appoints all other officers whereas other types all or some of the positions are voted in by various of the other positions and so on, again anyone interested can consult CoffeeMUD documentation for details.
The variety of governance types available in CoffeeMUD might even suffice for many types of organisation that otherwise might require an entire DAO in other contexts, it is quite powerful although possibly for totally arbitrary votes not enforced by the software one might have to use something the software does handle, like which room will be the group's donation room or even just which character gets which position with choice of actions to take being decided by which character gets the position.
One of the big advantages of using existing free open source games as components is any prospective players can dive as deep as they choose, even to the extent of running an instance at home, examining its source code to find out
exactly how it works, run simulations at home setting up characters with or without any gear or skills to see how different choices could effect outcomes and so on and so on and so on.
Basically players are free to become as expert as they choose with any of the component games before diving into a live Galactic Milieu instance/server of such a component to play "for real" / "to earn".
It has been iterated and reiterated over and over again that IXC is far from dead, seems weird you'd be surprised to find it still running and still in use...
Oh and finally, apparently Tartacus also has an intergalactic mining Corp whose planets are named Tartarus One, Tartarus Two, Tartarus Three and so on...
Add to that info the fact that Caesar similarly has such a Corp, with planets named Caesaria One, Caesaria Two, Caesaria Three and so on and it becomes clearer why they imagine they might be powerful enough and/or rich enough to launch a New Roman civilisation with
its own accompanying currency...
