In regards to roles it all depends on what anyone can imagine.

Initially we need coders to build the thing. Design work to redo logo, educational material to explain the project simplistically for onboarding. Discord or telegram moderators. Social media or marketing peeps.

If we want the system to spread to other regions, people could act as embassies, or torchbearers to help spread to their region. When other regions are created, that opens up possibilities of new job types aimed at cooperation and coordination between regions, trade deals, or whatever.

As an investor in the region, holding DARMA you still get to vote whether you live in the region or not, and also will get airdropped tokens from projects created from it, giving you network control over any systems built, and voting functionality within the system, or however they are designed.

DAOs although created under the DARMA project, could operate outside of the Merseyside region or globally.

There will be lots of umbrella projects created by the DARMA project which will have their own defined roles depending on the project.

Easy roles
Vocal supporter - cheering everything on
Silent supporter - nodding head at computer screen

I hope that defines some sort of conceptual idea.
