RogEE: Add-ons for ExpressionEngine 2
Pulls data from EE wikis (into EE templates). Basically, this is EE's Channel tag, but for wiki content.
Wikibits is still in development. You can see my plans for the plugin archived at the EE forums.
The code is neither full-featured nor stable. If you'd like to contribute, please check out the Mercurial (Hg) repo at BitBucket and contact me!
