PBWiki Adds New Features (FREE)
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.
