As more people are thinking about developing structured courses of teaching and training Web-based materials in chemistry, so the need arises to think how such courses might operate in a multi-author, multi-course, many student and symmetric ( ie students need to submit files as well as read documents) environment. None of this is specific to chemistry, but it turns out there are many interesting tools emerging for this type of application. We have heard very good reports about WebCT http://homebrew1.cs.ubc.ca/webct/ although there are other (perhaps more expensive) products such as FirstClass etc. Does anyone have any experiences of using such tools? One of my concerns is that we will all end up using different tools, and the global reach of the web will start "Balkanising" into lots of little local Intranets, all pretty much incompatible.
