Email your future self and don't forget anything ever

There’s a simple way to get email event reminders without being tied down
to particular software or device. The free, web-based Yahoo! Calendar
(http://calendar.yahoo.com) can email or text message you event and
task information on the days and times you specify. Create a time-based
reminder file that emails your future self the data you’ll need to know at just
the right moment in time with Yahoo! Calendar.

NOTE Like Yahoo! Calendar, Google Calendar (http://calendar.google
.com), is also a free, web-based calendar that can send reminders via email or
SMS (Short Message Service, also called text messaging).
