>>manned/umanned<<

Unattended was also the first thing that popped into my mind (thanks, bel ) in that particular instance. However, I really never contemplated the dilemma of manned/umanned before. Because, I guess, it's one of those terms and phrases that have reached beyond their original genderism to become, in effect, agenderal, if you will.

And remember..."going postal" is always gender neutral.
