I haven't figured out how to "edit" this as I am not given this option when I log in, even though it is my presentation. So, I will give some more information as part of a comment. I have prepared a home page for the presentation at: http://www.siu.edu/~cesl/teachers/pd/hb.html I am collecting sources, etc. here: http://thisisyourbrainonweblogs.blogspot.com I hope you can join me at Tapped In, at the stated time! -Tom
