The commitments I have mean that I haven't the time to spend hours sorting out difficulties. Possibly there may need to be more support in the future with the use of a trouble shooter for each department to solve such problems. Similarly I know that I face hours of work in getting the next stage of Top Class working. Issues of access need addressing. One difficulty was that students have different abilities to access the materials.
Some students have Internet access from home and of course from work.
However, those students who work in places or jobs where the Internet is not available often complained to me that it was 'not fair'. Possibly there is some inequality given that the materials are only available electronically which gives some students the luxury of easy access. I always pointed out to students that access was always available from the several laboratories around the University and from the University Library, but it is perhaps an issue. Another side effect is that once you post information, advice and articles, it is open to other academics to view what you are doing. I had some colleagues making comments about some of the work I had posted onto the web site, suggesting they would have done things differently.
