The Cryptography Stack Exchange recently went into private beta and we're trying to figure out what overlap there is with Mathematics. The Mathematics FAQ seems to imply that questions although mathematical in nature should be kept on Cryptography if they are not general math questions, and also fairly explicitly states that research and design questions should also be kept there. What is the Mathematics community view on this?
Additionally, it would probably be prudent to update the Mathematics FAQ once the Cryptography site reaches public beta, if certain questions are to be migrated there.
