For the user list, yeah, doku wiki can do a lot of things. I just glanced through the list of available plugins. Issue:
I tried doing something in the wiki: there seems to be an issue: if I create a page it works perfectly fine. But when I try to modify one, it gets "saved" (as you can see if you edit the page again) -- but the changes do not seem to appear -- you still see the "previous" version. The documentation clearly states that the changes should appear instantly after hitting save. I am thinking either some sort of "confirmation configuration" or some sort of "caching" happening (wild guess). For example, in the playground, I added a new sentence paragraph but it is not appearing.
