RTC SCRUM email notifications

I am familiar with the email templates and the user profile options when it comes to out-of-the-box email notifications. However recently I inherited a project with the SCRUM template. I was told that it should automatically send an email notification to the new Developer when the Developer field was updated. It does not.
Does anyone know if this is a built-in feature of the SCRUM template.
We are using RTC v 4.0.5.
Thanks.
Accepted answer

If it's the work item, I don't believe there is a Developer field in the SCRUM template (there is an owned by), so it's possible the previous administrator added that field. Either way, unless they've written a plugin for additional notification, email notification is governed by the user's profile settings.
If emails aren't being sent when the user is added to the Project/Team Area, you should be prompted to send an email when adding the user. In that prompt, if it won't allow you to send them email, email notifications could be disabled in your repository.

Thanks for your quick reply.
Indeed the normal emails that I know of (owner, subscriber... ) are working fine.
I believe that you are correct.and the verbal information I got about the additional out-of-the-box SCRUM specific email when the Developer field was populated was misguided.
I admit to doing the same thing in other circumstances -- ie. something that I was using years ago worked a certain way and I remembered it as the way it normally worked (not cumstomized) and that's what I told everyone years later.
We've got the developer field. That's a start. I don't suppose anyone knows how to send an email to the developer listed every time that field changes that they could assist?
One other answer

( AFTER the owner entry is set, the next time the owner will be notified when it is changed)
this class of notifications has been requested for a long time.
I have proposed we form a user group to define the requirements and create such an extension we can all use (open source)

edit: you can't use javascript as there is poor/no support for manipulating the contributor (aka user) type fields
edit 2: I don't see a 'developer' field in any workitem in the scrum template
