Someplace in your computer you should have a "note pad." The nice thing about a note pad is that you can keep little notes to yourself on it. So that when you need the information it is handy, you can keep "note pad" in the tool bar (located by the start button) when you arn't using it. Now practice putting some of these words onto your note pad.
