Wiki found.

I think MindTouch would be an ideal wiki type for my public library. All employees would use the wiki; many are not very tech savvy. The wizard at WikiMatrix found 13 relevant wiki types that could be of use at this library. The most important factors in my decision were cost and an easy to use,  WYSIWYG interface.
Library staff plan to use the wiki as a resource guide for library policies.  Anything from circulation, handling donations, or how to handle unruly patrons will be addressed in the wiki. It is understood by the staff that the purpose and use of the wiki could develop and change once it is established. MindTouch is an ideal fit because it is hosted software with commercial support, allows for endless edits, preserves page history, has a WYSIWYG interface, and allows users to comment.
