How is a Wiki Different From other Content Management Systems?

Wikis have the added ability to:

• Allow multiple users to collaborate on content
  • Can even be open to the public! *
• Content structure loose
  • can be changed on-the-fly
• Content is versioned
  • Changes to content are saved
  • Unwanted changes can be reverted
• Designed with knowledge sharing/documentation in mind

*Note that the SICAS wiki will NOT be public! It's intended for internal use only.
