Desire2Learn (D2L) User's Guides and Tutorials

UPDATE: I have moved to Google, as many of my institution's groups are hosted there. I'll still check back here from time to time, but for the most up-to-date information, please visit Accessible Design Google Group

Included below are archived copies of D2L User's Guides prior to version 9.0. Even if you don't use D2L, you may find useful tips for designing accessible, intuitive course environments and content. If you use D2L already, you may want to join the D2L Community to access the most recent user's guides and other community resources.
(Presented atD2L Fusion 2010 with Ken Petri, Sandra Earl, and Janna Cameron, includes CSS templates for HTML design)

Why bother with accessibility?
