TWiki is a web based collaboration platform where users can create light-weight applications without reverting back to programming. This can be done by people with modest skill sets using the functionality of the TWiki core and installed Plugins.

As in Movable Type, you can customize the look with skins. It is not as easy to install as some other Wikis, but you get a lot of flexibility with currently 130 Plugins, 35 add-on packages, and 27 Skin packages available for download at TWiki.org.
