Dr. Rolf Becker established this wiki to support his teaching activities at the Rhine-Waal University and beyond. teawiki.net
is based on Dokuwiki, a lightweight, open source, easy to install, deploy, migrate and use wiki platform. No need for databases or complicated installations. Access is controlled on file system level with ACL (access control list). My favorite!
Thank you very much, Andreas Gohr from splitbrain.org, for this great piece of software !
