A minor adjustment I made in this site's design last night caused it to be unreadable in most older browsers. What happened — this will only make sense to those of you who know HTML coding — is that I neglected to close one "table" tag. The page still read fine in the current versions of Internet Explorer, Netscape, Opera, etc. But it didn't appear for the users of some older versions of those browsers until a couple of them e-mailed me and caused me to find the error. I thank those alerted me and apologize to all who were inconvenienced…and I urge you all to upgrade your software. In the next few months, there'll be plenty of sites out there you won't be able to view.
