Gmail now supports "Read Receipts" which allow the sender of an email message to request a verification from the recipient that the email message has been read. This was one of the features that people missed when we moved from Groupwise to Gmail, so I've turned it on for the oregonsd.net domain.
Instructions for using this feature are available at http://support.google.com/mail/bin/answer.py?hl=en&answer=1385059
