Internode Monthly Usage Meter is a popular download usage management program, it is easy to use and has a load of features.
It is one of my favorite traffic management applications; it sits in my system tray and notifies me about the traffic overruns. Unlike other programs of the kind it calculates the traffic usage in relation to the days left in my billing period. This makes it very easy to know whether to slow my downloading down so that I would not be slowed to dial-up speed, or to use up the accumulated download before it expires.
It also offers graphs of the download usage for the past thirty-one days and overviews of the monthly totals for the last thirty-one months. The application can also be set to monitor your Internode e-mail account and notify you about any incoming email.
One of the best features of Internode Monthly Usage Meter is the customizable list of the Internet radio stations, which you can find in the 'Setup' tab. The list of radio stations is also easily accessible from the right click menu in the system tray.
