which wiki to wiki...

[recursive.forest-Re5JQEeQqe8AvxtiuMwx3w at public.gmane.org (Samuel Baldwin)]

werc is the only wiki I've used successfully over time without going
completely nuts. I don't know how good it is with variable
authentication (as in, different people are allowed to do different
things), but I'm sure there's either a plugin for it or it would be
trivial to add, since werc is only about 200 lines long. Some of the
site will say you need 'Dirdir' to make it a wiki, but Dirdir has been
included in the main werc distribution. Some form of history tracking
should be trivial as well, just appeding diff's of each change to a
file and then reading it out when needed. Come to think of it I may
extend it a little to give it these features which are kinda necessary
for larger projects.

werc.cat-v.org is an example, as is all of cat-v.org
