I visited www.wikispaces.com and opened an account. Select "New Wiki" and fill out the following.
This page is self-explanatory. I will proceed by adding a new page by clicking the + symbol to the right of "Pages and Files".
Type in a page name. I would add a tag by typing "Table of Contents" and then choose "Create".
Adding new members is easy. Just type in their email address, message, and send.
Choosing "Manage Wiki" will get you this screen. This is similar to Control Panel in Windows. You can make adjustments to all aspects of your wiki from this point. Let's go to "Files" under "Content" next.
You can create new pages, upload files and create tags that will assist in searching and navigation. There should be a similar component in Canvas, where you can do the same things.
Return to "Manage Wiki" and choose "Look and Feel" under "Settings". On this page you could upload a logo for your department and choose the themes and colors.
This is where the WYSIWYG editor comes into play. You can choose one of the themes and modify to suit your tastes.
I visited several different wikis and chose Wikispaces because of good reviews, ease of use, and a very strong "Help" section adjacent to the "Sign Out".
