You will need to create a text file "alerts.txt", inside DIR of the files that start with "alert"
You cannot send the same alert twice in a consecutive period.
To send an alert, you will need to go alertSubmit.php?message=message here
Use method GET on a form, manually do it or change it to POST and post it via form.

Also, I know I didn't leave my cPanel information on this script :)
