Many don't know squat about the Web or how to use Netscape. Mostly not knowing how to do searches through any machines. No problems encountered I have never heard of any complaints. Once again, I really haven't had any of these types of questions asked of me. There are no major problems.
Major problem is when people try to download files.
Students don't know how to download files from a WWW environment. The instructors need to know what they're doing, basically. Put more information on training pages. Students should be taught at least the basics because site cons cannot be expected to teach every student how to use software. Make sure students receive the appropriate basic training.
