I was very wrong in introducing my friend's nickname to this site, my friend now asked me to change the username on this site, but I can not find such an option anywhere, tell me how to change my account name please

Only an admin from the booru can do that, the best you can do is to send them an email requesting to change your username, they usually answer in a couple of hours, or you could make another account.

I could make a new account, but in any case I need to change my nickname here, but how do I send a message to the administrator?

The admin for this booru is illusioncards but he's not very active here anymore, but there are others admins that helped me before and you can contact them from this email ([email protected]) just send them an email explaining your issue and wich booru has your account then wait for their reply, i hope they can help you.


Regards.

Thanks for the help, right now I'll try to write to them, thanks again for responding

I sent everything, I will wait for an answer, again thanks for the responsiveness :)

You're welcome, i'm glad i could be of help. :)
