Buzzen Update:Great news! Buzzen has finally resolved the long-running issue that was preventing service emails from reaching MSN accounts. Registration emails, account notifications, and other important messages should now arrive as expected. If this issue kept you from joining before, now’s the perfect time to come back, sign up, and get your Buzz on!
