[ale] Web Based Calendar

[cfowler at outpostsentinel.com (Chris Fowler)]

Looking for some software.

I want to install a web based calendar system on one of our CentOS 5.3
machines that will allow everyone to log in, update their calendar, and
then everyone see those updates.  

I'm looking at it more like a huge white board that is a calendar that
people write on with an erasable marker.

Any leads?
