WoWus (World of Warcraft Updating System) helps you keep up-to-date with the latest add-ons by scanning your add-ons folder and displaying any relevant updates that are required. You can choose which updates to apply and WoWus will then download and install them for you - all with the click of a button. It also has add-on management features and back-up support for updated add-ons.
