I asked this question on Travel.SE as an unregistered user last year. Since then I became a regular visitor here and created this account. Recently, I stumbled upon that old post which is now one of the frequented questions on Travel.SE. I also noticed that the question and the top response (also by me) gained some rep points. Now I regret not registering earlier. Is it possible to add that post (and the rep points) to my current profile? I am quite certain that I used the same e-mail id to post that question as the one I am currently registered under.

Supply some details as necessary, and point to this meta question as well, if you like.
