Exporting PS Save Actions for Mac and Windows

Hello,

I want to share a "Save for Web" action script that I created for other users in my group to ensure they use the same settings. Some users are Mac, some are Windows.

How do you make the desktop location generic between both platforms? For instance the action script seems to record the path all the way up to the local root Macintosh HD and includes my user directory name. If another users imports that Action script, they will get a directory not found error. Is there some shortcut I can edit into the script with a text editor so the location is common between platforms?

Something like ~Desktop?

Guessing.

Thanks for any help.
