After furious head scratching, valtal asked:

| Am running XP Pro, single desktop comp. .users on two diffrent
| desktops want to share a "public calendar". Is it doable? all help
| says you need MS exchange, a single computer does not have it. Seems
| there should be a way of sharing an outlook calendar with users with
| diffrent screen names on the same computer.
