We've had this happen several of times now and it is not good...  We get an end user who submits a new ticket (marked as not a rush) and our support group gets notification via email that new ticket has been submitted.  It doesn't necessarily get assigned to a tech immediately (simply because it is marked as not a rush), and in the mean time, the end user that submitted the ticket has updated the ticket (either with more information, a request to close it, or something - but it is an update never the less).  No notification is sent that the ticket has been updated, and there are no visual clues in the "Requests" view that it has been updated.

There needs to be a notification mechanism for unassigned tickets that have been updated by the requester (or anyone else) that goes to the same group of people who receive the email with the initial ticket request.
