Subject Re: email within action

Depends on what you want to do really. As Guru points out you can use  
Web Services though that can grow unwieldy. For something light and  
pretty straightforward you may just want to use JSON (javascript  
object notation) or Xml HttpRequests. Have a look at the showcase  
project in S2 on how to use the Dojo toolkit.
