Hi moderators... There seems to be a glitch on the Inbox section of the control panel (sorry if it's already mentioned). It always shows "0" messages until it's clicked. Once visited, it shows the number of new messages.
This number does not dynamically update, it requires user intervention by navigating through the site or clicking refresh. We may add this dynamic action in the near future. If your waiting for a new message then leave your browser viewing your actual inbox, this will dynamically indicate that a new message has been delivered. Thanks for the feedback.
