If you're looking to make some of your content available in a wiki, take a
look at PBWiki, which just released some new features including a new editor
(which allows for linking, tagging and sharing) and includes page-level access
(control who can access a page, making it public or private), page folders and a
new interface.
PBwiki has some competition in the market in Wikia, SocialText, and WetPaint
but it is a solid solution for educators and businesses that don't have the IT
skills to make wiki's a reality. PBwiki is a hosted wiki, meaning that content
creators post their content on the PBwiki site. If you don't mind losing a
little bit of brand control, then PBwiki is certainly an option.
