Desktop Calendar/PIM/etc

[Travis Newman]

Sorry to crosspost from the forums, but there are 2 different audiences, 
so I thought I might also get some help here.

We're looking for a good Calendar/Planner/PIM/etc system that has popup 
alarms, and that DOES NOT require the app to be open, maybe just a 
remote app that takes up much less sytem resources (using some older PCs 
because we aren't loaded yet). I do have an old iMac that I'm basically 
using as a server, so I'm thinking of setting up some sort of groupware 
server there and having the program sync with that, if need be, and I 
must admit I just want to play around with a groupware server, but 
that's NOT necessary Evolution would be great, but I can't get it to 
alarm unless Evolution is open, and system resources, as I said, are a 
big issue. It doesn't NEED to look nice, but it would be nice  gtk2 
would be preferable, but it can be motif for all I care if it works.

PS: I wasn't speaking in the "royal we" at first, or going crazy, I was 
talking about me and my fiancee.

Thanks in advance!
