I thought we had agreed not to give complete solutions to homework problems, but apparently some people didn't get the message. If this is not explicitly in the FAQ, it should be. Once that happens, how do we make existing math.SE users aware that this policy exists, and what is a reasonable way to enforce it?
(There is an unreasonable way to enforce it, namely for a 2k+ user to edit the complete solution out. I would prefer not to do this if possible.)
