I think it’s a great idea! Documentation as a community project is a great one to tackle.
From a purely features-and-how-to-run-a-group-on-Discourse perspective, this is what I would suggest:
- An Admin can create a “Documentation” group
- We setup a matching “Documentation” category (maybe a new Community Projects top level category that we put projects like this under?)
- the instigator writes a kick off post and makes a call for participation
- the group uses the category and/or the internal group private messaging feature to communicate how to document and get work done
Somewhere in there, a kick off meeting over Google Meet or Zoom might be a good idea.
Let me know if you want to be the instigator of this! And/or write some more of your thoughts and see if you can find some people to join you in kicking this off. Another good rule of thumb is getting a minimum of 3 people to work on something together.
