Raj and I have put together a tutorial called "EMML in 15 Minutes" to help learn EMML. We also have created all the sample EMML mashups used in the tutorial on Presto Cloud (you need to be logged in to MDC) so you can run them and see for yourself. Please check it out and share with others via twitter, etc. Hope this helps for newbies as well as others.
As always, we welcome your questions, suggestions and comments.
EMML in 15 minutes is really great. Its very much learnable especially for beginners. It taught me a lot. It was great in helping me create a new cloud computing strategy as well. I would suggest that everyone takes the time to look at it.
