This is a good and very valid point, but I think that unfortunately for so many topics here in this forum, other platforms would be much better suited than this “discourse”. Thus I support both, the idea of having a proper wiki for guidelines, as well as stack exchange for responding to problems. Because I don’t agree that the [quote=“Stefan, post:6, topic:18538”]
“Accepted Answer”-plugin to the Fairphone Forum […] pretty much does what Stack Exchange can do
[/quote], since stack exchange ranks the answers according to users’ votes on how helpful they were. Considering that there are threads here with hundreds of replies, stack exchange would significantly increase the visibility of the helpful answers and make it much, much easier/faster to find a possible solution for your problem.
But to avoid information being scattered around the web, it could be hosted on the FP servers. Maintaining for example a wiki doesn’t need much of administration, so personally I don’t think that it would cause a lot of additional maintenance work. And like a wiki, also stack exchange is pretty much moderated by the user base.
