I like that you are looking at what others are doing.
I really like:
Totally Integrated Knowledge Infrastructure
Tightly Integrated Knowledge Infrastructure
Yes, Tiki is a groupware, a CMS, a wiki, etc. But in the end it's a knowledge tool. And our strengths are features and excellent integration (SSO, content reuse, consistent look & feel, etc.)
I was thinking of rotating banners. We could make so many, but something like this:
wiki (2 sec pause)+forums (2 sec pause) +bug tracker (2 sec pause) +blogs (2 sec pause)
= TikiWiki CMS/Groupware
Keep up the great work!
