That's a big point in having a wiki where you
don't have to
register. You actually have no, absolutely zero, maintenance, because
the users removes the spam.
You install a wiki, then leave it be.
We still need a scaffolding to propose structure as well as at least one
example documentation which will serve as a reference. Design is another
issue as vanilla Wiki pages are plain ugly. Hence, I am not doing it unless
I have time to spare (which I don't) in order to do it right. You and others
are welcome to try...
Best wishes,
