Synchronization may be a wonderful, stable feature. It's just that nobody on the message board has spoken up to say that they use it all the time, and it always works right. Nobody wants to be the first human test subject!

(That being said, I may try it after my next day of nursing home rounds. If so, I will update everyone on my experience).
Sharing templates, on the other hand, is easy. You can export them onto a disk, your network, or even post them on this message board (we have a whole forum dedicated to that kind of thing (Helpful Downloads)).
I can tell you that exporting templates is done from the template editing screens. If you are having a particular problem doing that, someone like Bert would be a great person to ask. (I am a relative newbie to the User Board).
(Hmmm... there sure are a lot of parentheses in this post (but parentheses are fun (aren't they?))!)
