New to Lithium and I see the community has forums, blogs, Q&A, and groups...but there is no mention of wikis. Does Lithium have/support wikis and just call it something else?
You might get this from the documentation, but the best way to think of Lithium's TKB is like a cross betwen a knowledge base and a wiki. Workflows and permissions allow you to tailor who can participate and how. Then you reward them via leaderboards, ranks, and badges.
