Hi Steph, Dmitry, and other observers,
    Apologies for missing the already plugged cartridge on the list.
To help catch things on our end, we are now listing the entire
contents of the cartridge bay in the plugging email response, rather
than simply acknowledging the request.
    I guess I would have preferred you called me when this was
discovered (presumably during the afternoon checkout).  I could have
sent someone up to take care of the situation, rather than have a
failed attempt with the wookiee (the hardware is functional -
apparently the cartridge was still applying force to the latches from
the mast either being too high or low w.r.t. the rack - there were no
problems putting it away this morning).
				Cheers,
				  Dan
