I'd really encourage anyone who works with ETM either developing new stuff 
or maintaining an app that uses it to read and play around with that and the 
other widgets in the app.

Understand why things are connected the way they are, use the VIEW macro to 
see the contents of each intermediate model etc.

All the best,

Steve.
