I am in the hunt for a 2.0 open source wiki or at least a solid 1.1 .  I looked around for about 3-4 hours last night and tried a few and was able to convert FlexWiki to 2.0 without too much trouble.  I am currently looking into the features and right of the back, I dont like the UI.  I want more of a user system for full collaboration.  With these open source third party web app modules, I want to give rainbow more applications it needs.

 So far Rainbow 2.0 will have :


Forums : A 2.0 improved Yet Another Forum
Blogs :  A 2.0 improved SubText
Wiki : A 2.0 improved version of TBA

This will complete rainbow's community modules.  I am also looking into open source project management tools like issue/bug tracking.

Please leave my blog with suggestions for open source .NET wiki's or any .NET open source web app that would benifit from being inside a portal framework.
