nothing. we will be providing a "full history planet" at the last point 
before the changeover itself to ensure that all data contributed under 
CC BY-SA is available. all previous planet files will, of course, 
continue to be CC BY-SA licensed.

i think it would be good to have this hosted on a read-only server 
somewhere, as there may be people who change their mind post-vote and 
need to "recover" their contributions. this process would be helped by 
making access to the old contributions easier.

cheers,
