Directions must be clearly spelled out so that the experienced and the novice can use them without going out of their minds. This is tremendously important. Download time must be reasonable. Your site doesn't need to load in 3 seconds or less, but it should load on a 28.8 modem in less than a minute. This seems reasonable to me.
Design allows for easy visibility and reading of text.
If your site has text over a busy background, don't bother me with it until you change it. I like my eyesight just fine, thank you. Navigation must be easy to follow. If it is, just bookmark this page, and submit when it's finished. While it is not required, I would appreciate a link to this site.
