FYI - I will be giving a webcast on Workplace Designer this Wednesday. While the title is kind of lofty, I will spend most of my time going thru some handy tips and techniques on using Workplace Designer, based on a couple of samples that can be downloaded and used immediately. It should also give you an idea of some of the power in WP Designer, even if you are new to it. I also cover a little bit of the architecture and runtime environment, how the document store works, and some of the unique challenges of scripting in a portal environment and how to solve them with Designer techniques.
