I have found that the Help Desk responds very quickly to requests. A Guide to WebCT Version 3 from Laura Gill and Wendi Jollymore. Both WebCT newbies and veterans are sure to be impressed and informed by this Interactive Demo . The new Reference Manual for Designers has nice screen shots.

All documents are available in various formats.
You can download them, print them or simply view the pdf files online whenever you need to. A few of these documents consist of a huge number of pages - you may therefore opt for viewing them online or downloading them to your laptop. WebCT seems to have two main gateways to their site. The WebCT Home Page offers extensive info, with useful announcements and links. So, you're working in 3.0 and you get stuck.
