Reminder is a useful little Dashboard widget that allows you to create quick reminders to yourself in iCal, rather like a local version of the Reminders feature in Backpack 
.
Entering the reminder is easy.
After installation, just call up the Dashboard, enter the time after which you want the reminder and a summary of whatever you need to remember:
A reviewer on dashboardwidgets.com says, “Just the most useful widget so far for me!”
Reminder is freeware and is available from the developer’s web site
