At the January meetup, Dennis Lembree of CheckEngine USA gave a splendid presentation on web accessibility. Topics included the definition of the term, general issues, guidelines and law, and advocates. You can get the web accessibility presentation on the CheckEngine USA web site, which is available in HTML and PDF formats.
I intended to be a first time visitor to the meeting, but some bad weather and other factors, plus the distance from my home base in Rochester, made it impossible that night. I am sorry I missed it and itend to make the next meeting. I have already checked out the presentation Dennis has on his website.
