Yesterday, I answered this question on Math.SE and Zev migrated it to Physics.SE. The OP had an account there, and Zev commented that "If you need help associating an account on physics.SE, you can flag your question for moderator attention". The question has since been associated with the OP's Physics.SE account.
I created an account there and flagged my answer for moderator attention, asking that the answer be associated with my account. It has been several hours, but my answer has not been so associated. Is it possible to do this with an answer, or should I stop pressing the issue?
I just got a comment from dmckee$\,\blacklozenge$ that "Fixing the situation outlined in your flag is beyond the power of a diamond moderator. For the moment I am waiting to see if some daily script will correct the situation. Once it is clear that this will not happen, I will escalate to the team."
