The archiving dialog specifically says:
You should always archive on the same computer. This ensures that you will have a single archive file containing all of your historical data.
So it's natural that I'd only want to archive on one machine. But, if there's an obvious "don't ask me this again" or a setting in OmniFocus Preferences to disable it on other machines you're syncing with, I can't find it.
Can someone point me at a way if this is possible?
