I've been playing around with the email templates in FIM 2010 and one of the cool things is that you can easily add information about the subject or requester of the request. To use these values you can use the following notation in the templates:

• [//Target/Attribute]
• [//Request/Attribute]
• [//Requestor/Attribute]
• … ?

Some examples:

Suppose you have a Synchronization Rule which is added to a User object using a workflow and MPR, then:

• [//Target/DisplayName] will give you the displayname of the user
• [//Target/Domain]\[//Target/AccountName] will give you the domain\accountname of the user
• [//Target/Email] will give you the email address of the user
• [//Requestor/DisplayName] will give you the displayname of the user of this request: in this case the Built-in Synchronization Account
• [//Request/DisplayName] will give you the displayname of the request

In my FIM deployment I use this to send email notification to certain persons. As an example I send an email to the exchange team when a user is "deprovisioned" by FIM so the mailbox deprovisioning process can be triggered. Of course there are many other possible scenario's to use this functionality.
