This script does work, but it only works on one day out of the month.
What happens is that the script reads the date from the browser, and if it equals what the script wants, it displays a message. You could set it to tell you to pay the rent, call someone, or to get a birthday present. The alert comes all that day. Grab the script. It will be quite obvious where you change the date to get a new day to pop up the alert box.
Please note: This script is being offered in simple text format. When you click to Grab the Script, the text should display. Internet Explorer and AOL users may get a blank page or the script may run and produce the effect. If this happens, choose SAVE AS from the FILE menu and save the blank or compiled page.
