While Moodle isn't the most intuitive of LMS's, I still severely underestimated the difficulty learners would have doing simple things like uploading files -- perhaps because so many of ours are recent and unwilling digital immigrants (refugees may be a better analogy).
At any rate, to save my own sanity I have started creating help files consisting not just of a glossary (which, btw, would be a great resource to have available to all of us as an uploadable XML file) but also Flash demos, produced in Wink. The first of these is now up here. Would've been nice if the HTML editor didn't keep stripping the Flash code from the glossary entry -- but making it a separte resource works OK. Would love your feedback; I'll post more as I find the time to create them. Am looking forward to the new release of Wink, which should have audio -- rumors of a beta test run rampant!
