tho' a bit afeared to step in the middle of mg and sjm, I can hear the middle one as being ok, because each user implies a group of users, though being used one at a time. so their works for me. (well, I'm pretty sure I've used it a few times... )
the third example works very well, as well. nise and concise.
btw, I'm a unitarian-universalist.
