Here is the presentation about testing Web apps with Selenium RC.

The presentation has three parts. The first is a very generic introduction to Web testing in general and should be beneficial to people who want to get an orientation in the field; the second part introduces Selenium RC, this should be beneficial for people looking at concrete test products; and the third part shows how to extend Selenium RC with custom code, which should be beneficial for people committed to Selenium RC.

The slide show is double length, first the normal presentation slides for a quick overview, and then all the slides again with notes which should make it easier to get to grips with the material without the oral narrative.
