Hi all,

I am planning a small office rollout for a bunch of windows PCs,
running XP with Outlook express. I want to use linux/free software as
the backend suite. I have already decided on Samba, postfix, qmail for
email and file sharing.

 I am still looking for an application that will allow my users to
share contact databases and calanders. I am impressed with webcalendar
 (webcalendar.sourceforge.net) and think i will roll with that. Does
anybody else know of any other good applications for sharing business
information in a small office? I like php, web-enabled, applications
very much.

thanks in advance,
erich
