Sarah, my understanding is that MapRoulette does not support it -- I cannot
upload the following:

For Object ID nnnn,  change one set of tags for another -- accept or
decline?

Would be great if I was wrong.

Yes, the community can do it, the question is - should it?  Given 2
challenges, one that requires some thought, and the other that require
clicking yes without thinking, shouldn't we opt to the one that computers
cannot do?  We seemed to assume that donated time is free, unlimited, and
has very little value. I feel we should treat donated time as the most
precious and most scarce resource we could get.
