I have a project that I think wiki would be great for, and the idea is to have more tabs in the wiki in addition to the discussion, to organize the interactions. For example:
There would be the main wiki that we'd like to call a course module, then the discussion tab is fine it can be general comments, but then I would like another tab to specifically post questions and have the course author or users be able to answer them. Then I'd like a tab where users could post links to data supporting or refuting the idea in the course module, then a tab where users could review the module and then finally a tab where one could post and analysis or a rebuttal of the module.
The idea is a sort of source build course to encourage discussion and debate, but keep the different interactions separate. I see wiki already has tabs built into it, would it be possible to expand it as I have described?
