Looks like my next project (whether I want to do it or not) is to work on making our department websites accessible by everyone. Something called Section 508 of the Rehabilitation Act. The hospital is also going with W3C's Checkpoints for Web Content Accessibility Guidelines 1.0.
It doesn't look like it will be too bad. I think I should be able to accomodate the requirements with a few style sheet and template changes without too much pain. I suppose I should go ahead and run it all through the Validator while I'm at it.
