How do I change my text on the Description Page?

Click on the description page in your Control Panel. Place your cursor at the beginning of the line of text you want to change in the text box, holding the left side of your mouse down scroll to the end of the line of text you want to edit and let go of the mouse. This section will now turn blue and you can just type the new text in its place. If this is not successful, click at the beginning of the line of text you want to replace. You will see your cursor flashing, press the delete button on your keyboard until the text you want to change has been deleted, then just start typing the new text.

The same applies to all text boxes in your Control Panel.
