Reply to: RE:Reporting of accessibility problems Harvey, Thanks for the summary, I'll be interested to hear how other people respond. I think one of the other issues to raise is that not all of the guidelines are readily quantifiable by a computer program. Also, we are abandoning the four star rating system in favor of pass/fail based on the analogous argument: "1 step or 100 steps, it's still inaccessible." David Clark CAST, Inc.
