Many businesses and organizations want a web calendar to inform
customers or members about events as well as to register people
for events and classes.
When someone visits your site and think " I just know Mary would love
this site' they just hit the Tell-a Friend link and a form allows
them to send the site URL (clickable to take them right there) to
as many as 5 friends.
They can personalize the note as well. Every site should have
one!
