Taking a peek at the GWCommander software.

Looks useful (especially the holiday things on the calendar)

But it seems that it runs as a daemon on the Windows machine.

The question I have, is do you need to keep this up and running if you just want to blast out the holidays on the calendars?

I can understand if you have a recurring task that runs (in which case obviously one would want to run this on a server vs. a workstation), but just wanted to make sure.

Unfortunately the link in the PDF that came with it takes you to a site without the "support" link.
