I would like to build a new module for DNN 6.2+ that periodically check to see if a user has any new Messages or Notifications.   If the user does have something new, a window will pop up to inform them.

The user will have 2 options on the popup:  Go to Message Center, and Cancel

If they click Cancel, the popup window will not be shown again until they have an additional new message/notification.

My question is this:   Using the DNN API, is there a way to get the timestamps for the last unread private message and notification for the current user?

Worst case scenario, I think I could just look at the appropriate tables in the database, but I'd rather us the API if possible.
