Germany has a nice legal entity for stuff like this: the eingetragener Verein, or "Registered Association." This is used for pretty much every village football team, so you can raise money, have a bank account, sign contracts, etc. It's also used for larger things: my first encounter with the form was in the 80's as an exchange student. The whole exchange program was an e.V. It's also used for a lot of things that would be Foundations or Nonprofits in other countries.

The catch, if it's a catch, is that you have to have at least 7 people and there's no way to be "in charge" if four of them think you shouldn't be.
