I know this is a mess right now . . . it's hosted on a different server, and it's going to take a bit, but it's all coming back, hopefully with a better layout. Don't worry.

Let's see how this goes! Oh, and I'd like everyone to respect each other, so try to refrain from flaming. Thanks!

Also, while I'm sometimes unable to respond promptly, I do make an effort to respond to everyone. There have been a few people that I've tried to respond to, however, who didn't give me a valid email address, and my response bounced right back to me. Fortunately this happens seldom. If you wrote and haven't heard back, this might be why.

• April 27, 1997--Having only been recently introduced to the concept of "browser-safe palettes," I'm starting to recreate the graphics on this page with this concept in mind. I've had a few complaints in the past about difficulty in seeing some elements here. I just chalked it up to differences in browsers. Hopefully keeping the color palette within the range of colors that all browsers can display will help. Don't expect it all to be fixed at once, but if there's something particularly bothersome, let me know and I'll make it a priority.
