Hello office-mates in M104-105,
According to Anna,
"Custodial Services has asked that the boards be erased, so they know
for sure that the boards are ok to wash. They will not wash them if
there are any equations written on the boards.
and I am assigned the duty to ensure an empty blackboard every wed.
night. I suggest everyone just erase everything after *each* use, just
in case I forgot to check.
Regards,
Man Hong
