"Applicant Accepted Offer" means you have been accepted. I called the Grad School office about that, and received my letter in the mail about a week later. Congrats!
Lib1845, have you heard back from anyone? I applied to the MSW/MPH program as well, and have heard from MPH, but not MSW. Who did you email? I've had luck with GradAdm@uga.edu which isn't specific to MPH or MSW, but they were able to confirm that all my info was received. Good luck!
