Wikis that use a wide variety of user interfaces and navigation can confuse visitors, who may give up looking for information on the wiki. The ability to choose a custom theme for each space (section) of the wiki may encourage creativity and unique branding, but visitors to the wiki will need to re-learn how to navigate each unique section.

Users will stop using the standard navigation functions in the wiki and revert to the search function all the time .

Encourage space/section administrators to use a consistent theme for their section of the wiki. Color scheme differences are okay, but inconsistent navigation should be avoided.

• One Wiki space per Group - Providing a wiki space per group will work most effectively if the visitors to the wiki still recognize the group's space as part of the overall wiki.
