Duane,

You asked for problems, here's one in php:

http://open.appideas.com/Calendar/ phpCommunityCalendar is a pretty nice
system, but when you go to modify an event, all you have to select from is a
list of event titles.  If you have similar recurring events, you have to
guess which one is the one you're after.  If you can modify this so that the
pick list includes more info, like maybe the DATE, several people will be
very grateful.  There has been absolutely no response from the "support"
list, except two other people with the same problem.
