Please locate any possible account information for https://mathoverflow.net/users/44949/m-shahryari and merge into the current account, should that be possible. he had assumed that things went wrong because of FaceBook; who knows? Anyway, I told him at https://mathoverflow.net/questions/158444/example-of-non-commutative-ring-of-characteristic-5 that i would post a request on Meta and then put a link back at that question.
I have just put in a request to merge 29488 into 44949, with the latter to be made the permanent profile. The request should be processed in a day or two.
Update: apparently the merge has now been completed. (It's amazing how cumbersome the process actually is.)
