The top bar message box will now serve for a new purpose. Every notification output from the chat box will be moved to the notifications bar in the future.
We have added a notification settings page which you can find in: ERPhone -> Gears icon -> More settings. These settings will allow you to widely configure how you want the notifications to be displayed. If you like the old way of using a chat box for everything, you can easily opt out of this.
The /showmsgbox command is no longer available.
