This site is a complete rebuild of ETEC523, with the original site having reached its operational limitations. As it has not been possible so far to transfer all of the years of content and presence of past ETEC523 students to this site, we offer the following link to the “OLD” site as a place where valuable research can be done on all of the topics and discussions happening here now. The OLD site doesn’t work in quite the same way, but you should be able to find things of value easily enough.
