ToDoList Help Page
Once you've downloaded ToDoList you'll find a shortcut to it in the start menu. Look under start>programs>netboffin.
Click on the shortcut and ToDoList will start. Enter a Task in the textbox at the top of the form and press Enter(The Carriage Return key at the right hand end of the keyboard), and it will appear as an item in the list below. To remove the item simply click on it and it will disappear.
ToDoList is built with simplicity in mind. The best way to use it is to move the shortcut on the start menu to the quicklaunch menu on your taskbar(the bar at the bottom of your screen).
