[nzlug] Calendar sharing

[Tony Wills]

Anyone have experience with calendar/appointment/meeting-scheduling type 
software for Linux (to run on a Linux server) ?  I'm looking for something 
that will send reminders (maybe even popups for windows clients) when 
appointments are due. And can allow people to schedule meetings, by sending 
emails inviting others to attend and awaiting their confirmation.

Some such programs intergrate with email clients, so I should mention that 
most of the users are probably running windowsxp with outlook, but some are 
using Macs and others will only have access via the internet.

Tony.
