We require approvals to enter our webinars. The approval email provides the requesters name but no email address. This helps us to identify who the person is. We also have multiple webinars with the same name throughout the day and the email shows the registrants time not the time of the local webinar, therefore, adding the webinar number to that email will identify the exact webinar they are trying the enter.
This shouldn't be that difficult to program-add and this would be very helpful.
