IBM RTC 6 CCM how Automatically subscribe users to work items based on the Team Area?

 I can help I know java and you could provide me the info about the api and how interact with the subscribers attribute may we could have something 

Doing the subscribing is easy.. once you have the list of users.  this is the problem.
where is the list. and what does the list contain, is it team names, member names, role names ...??
some that are interested in this extension want specific workitem types, and certain state transitions, and from specific team areas.

note that RTC keeps extension config info BY project.

and how do we think we should present that configuration to make this extension usable?

I think it needs a UI, (aspect editor), not just xml content in the process config.
(I have another extension that uses the xml approach, but its easy to make mistakes)

I haven't done an aspect editor yet, UI is not my forte!..

and do we want to 'subscribe' the selected user (let RTC send the email) or notify them (send the email).  If we send the message, do we support message formatting, like RTC, using the same template style? (and are there separate messages for different events?)
