Useful, Informative, Interesting
However, I would say that it should be done only when you are ready to allow remote connection; for instance; asking your friend to help solve an issue that s/he knows. Otherwise, it is best left deselected at all time.
Anyway, after recently converting to the Mac, I know I’ll never go back to Windows.
