The University of Delaware is using Serf to deliver five courses during the fall semester of 1997. Throughout this period, Serf will be fine-tuned to remove any startup problems that may be in the code. Early adopters (i.e., purchasers) of Serf will receive free upgrades to solve any problems. At the moment there are no known problems, but if you understand the nature of software, you know there must be at least one or two problems in there somewhere!
We'll be listening very carefully to feedback and suggestions from Serf users, and new features will be added to Serf on an ongoing basis.
