When the email notification is sent stating a request has been approved or rejected, it would make sense to include a couple of more things.
1) The text from the previous request
2) The action the last user took on that request
3) Any comments associated with the request (Asked for by BYU in particular)
4) The ability to click yes/no to approve the request
For schools that receive a lot of requests, this will allow them to live in email as opposed to having to click into the request each time.
