I realise that this question has been asked in various forms already, but I still have a problem.
I have an old MathOverflow account
http://mathoverflow.net/users/6827/konstantin-ardakovhttps://mathoverflow.net/users/6827/konstantin-ardakov
and a new one, created in the last week
http://mathoverflow.net/users/5791/konstantin-ardakovhttps://mathoverflow.net/users/5791/konstantin-ardakov
I am able to login to the second, but not the first one. I believe I've emailed the Stack Exchange team already a couple of days ago, but got no reply.
What should I do to regain access to the first account?
