Is there someone who can get this message to the ISS Crew through official channels?  I see that there are several school contacts coming up next week, and the crew often gets chatty with the ground afterwards.  Under normal circumstances that's really appreciated, but this isn't the case, and I worry that the crew might not consider that their system is part of the relief effort unless notified.
