No I don't use one but mainly due to the fact that the old data structure is still in place and I still need to move all the user data to a new location with real security settings. Right now everyone group has mod rights in most places.

I've started moving data but so many things going on I don't have time to dedicate yet to moving all the user data.

Very few people save to the My Documents they've been told many times not to save locally, so most don't now days.
