I have a home network with 3 computers on it. What I need is software or something to have an appointment book/calendar on each computer so I can keep my schedule on it. But the trick is I want to be able to let each appointment book/calendar open and still update when a change is made to it on any of the computers. I have my main desktop set up to store all the documents and files on it so the other 2 computers can access it so it could kind of act as a server if need to be. I tried using Microsoft Outlook but it does not work since I don't have an exchange server. All 3 of the computers are using XP Home.
