That was the fastest ever introduction and code-dive to anything I have ever learnt!

Thanks a ton, Ron.

Just one suggestion, towards the end (Composition) when you are setting property for SumAmount activity your self-video was blocking the view of the property window. With the speed at which you were presenting I had to replay that part to understand!

Good to have you back, and btw your Workfflow learning guide on channel9 rocks!
