Howard - I was considering writing a tutorial for Tapestry. If you want to send me your notes or suggestions, I would be happy to start collecting input. No guarantee on when I can finish.

I'd like very much to discard it and start from scratch. I can keep up with the Tapestry coding, but I'm getting dragged down by the weight of keeping the documentation up-to date. I think the Tutorial starts ok, but runs out of steam too early. I'd like to scrap the Border and do something at least three seperate chapters on building components ... possibly instead of creating fresh new components, so how to re-implement existing Tapestry components. The three chapters would be: components with no body, copmonents that wrap other components, and components with their own template. But I really want to work on Sabertooth!
