I must do more research into how to do all this stuff because it is hard for me to get my head around it all. The spirit is willing but the technical acumen is weak.
That is supposed to be part of the appeal of various forms of "group", from small guilds, clans, societies, associations, political parties on and on all the way up to "civilisations"... They should be serving as means of decentralising the organisation of everything from help desks through acting as brokerage agents to provide their members with access to markets and platforms some (many even) users might not feel "up to" handling themselves personally.
Even such a to-some-folk simple thing a running a Horizon node of their own confounds some players, and not always for such "simple" reasons as their ISP (Internet Service Provider) defaulting modems to having UPNP (Universal Plug and Play) turned off; a lot of folk who are not already hardcore online-game players have no idea how to route incoming connections to whichever machine inside the house runs the thing the incoming connection is trying to connect to.
Clans, guilds, associations, parties etc - in short, groups - can help by maintaining such services for the benefit of their members, or even, potentially also for others.
Of course, groups are themselves part of a "slippery slope" back from total decentralisation toward centralisation, which is perhaps part of the fascination of the whole individuals versus societies or even civilisations tension.
