I just discovered an interesting way to use MS Outlook as a tickler system:
Start a new email to yourself, and while composing it go to View/Options. Go to "Delivery Options," check the box next to "Do not deliver before:" and enter 6:00 am and the date you want to be tickled. Then complete the email and send normally -- it will disappear to your Outbox, only to appear in your Inbox at the date and time you specified.
This is especially useful when you want to be tickled about something you receive via email -- just forward it to yourself and set delivery for the appropriate date.
Anyone else have Outlook tricks to share?
