A couple of free applications
Welcome back from spring break! Here are a couple of websites/applications that I think may be of interest.
Dimdim, provides easy to use web-conferencing. It's free and seemingly very easy to use. I can see this as possibly useful for applications other than conferencing in the traditional sense - collaboration, etc. The other site, commoncraft, provides short instructional videos ("explanations in plain english") on a variety of topics, such as RSS feeds, social bookmarking, wikis, and blogs. Check these out - they're free!
