I'm just learning the workflow piece within designer, so please bear
with me. I am definitely a n00bie! I am wondering if this is a
plausible scenario.

I have a form with a text area. Within that text area is a list of
application names. For any application that shows up in the list, I'd
like to send an email notification to the owner of the application.

So presumably I need some logic to parse the list(read the app names)
and then send a notification.

Where I am confused is, the best approach to take with this whole thing?
Should I use the data mapping activity and which other activities?
Should this stuff be put as pre or post mapping on whichever activites
it gets bound to?

Any suggestions or advice on where to get started would be appreciated.
