Hi,

I checked for the user management under gollumn. Unfortunately, there is nothing implemented. It would require some external handling of user managment to use gollumn as the main user-wiki.

As an alternative, I checked for different other wiki systems and It seems MoinMoin-wiki fits our needs as well.
Its a mature wiki system which works for many projects. Does user management and runs stand-alone if desired. Plus it is programmed in Python which might be a benefit for a python-centric community ;)

http://www.wikimatrix.org gives a nice overview of all kind of wiki systems.

However, maybe we have an expert here, who installed and maintained a certain wiki system and who is willing to administrate the wiki for micropython too. In that case use what is known best might be the best option.

As for the forum, if it takes to much effort now, how about a mailing list.
Mailman does a good job for many projects. People can subscribe and unsubscribe automatically and it would take a lot of discussions (including this) away from the github issue tracker, make it easier to follow pure development. A mailing list works fine for smaller (an larger) communities everyone can handle it much to his liking. It can be archived and accessed online and hence read passive in a similar way like a forum.

Any thoughts?
