I asked a question without registration and Prof. Bryant answered it but I can not accept the answer because it is not contained in my account.
I would be grateful if you guide me to accept the answer. When I was asking the question I was not familiar with the Mathoverflow.
Or, I would be grateful if dear moderators accept the answer.
An answer can only be accepted by the account that asked the question. Thus, you'd need to access the (old) account https://mathoverflow.net/users/86401/
If this is impossible for you, at first you cannot accept the answer.
But, it may still be possible for you to get the accounts merged (this could be a good idea regardless the present issue). To this end follow the instructions given at https://mathoverflow.net/help/merging-accounts
After the merge, you would be able to accept the answer in the usual way, by ticking the green checkmark next to the answer (as you did already elsewhere).
