hi folks,
periodically there is a request for information on this and other lists
regarding accessibility issues.  I came across this web site and thought it
might be of use to designers, planners etc.  The Universal Design principles
looked especially good.
Oh, there was also a listing for training for designers in universal design
on the web site of the Illinois ADA center, www.ada-il.org.  I'm sure many
states have similar sites.
