WebCT has an excellent Help resource at the top right of every WebCT page. When you click on that link a new window will open up. Usually the material in that window applies for the page that you are on, so the material will change. However, you can search for help in any area regardless of the page that you are viewing when you click on the help link.
You can only use this help if you are already logged in. The information provided in the following links should provide help with getting you logged in.
