Use internal linking. If you can handle simple HTML, enrich your site with internal links. For instance, link every assignment line on your syllabus to the files or folders needed in that assignment. Students will feel as if they always have at the ready whatever they need. Underestimate students' attention span for reading posted text.
Online reading is vastly different from the reading of hardcopy.
If you have long handouts, post them with a disclaimer, and make the material available on CD-Rom, on the campus server, on diskette, or in paper form. Expect to be regarded as a computer expert. Don't feel you need to be the computer expert.
