I have the following accounts, I seem to have found out: At math-overflow http://mathoverflow.net/users/37385/frode-bj%C3%B8rdal http://mathoverflow.net/users/30107/frode-bj%C3%B8rdal (At tex-exchange https://tex.stackexchange.com/users/24406/user24406 At physics https://physics.stackexchange.com/users/31950/user24406 At philosophy https://philosophy.stackexchange.com/users/5731/user24406) If the accounts at tex, physics and philosophy are irrelevant to my problem here, please disregard that parenthetical information. My two math-overflow accounts are connected with the same email address, and I can for inadvertent reasons no longer access the one listed first here which is the one I prefer to use. Could you please merge the two Mathoverflow accounts under the first listed here, and help me with access details and if need be by sending information I should need to [email protected]?
