Since I can't physically attend the ACS National Meeting due to another commitment, I'm delivering my presentation for the Using Social Networking Tools to Teach Chemistry symposium remotely. Bob Belford has graciously agreed to show the presentation video during the symposium, and afterward you can watch it again online (password: wiki). The presentation looks at how I used a wiki to transform a traditional educational web site into a community supported wiki, and runs 20 minutes. While you're watching (or after), please post questions in the comments section, and I'll answer as soon as I can.
