I could ask for the e-mail address of the account with the name "mpnooo", I am trying to log in but I forgot my password. I would very much like to ask for a quick reply.

Moved: Not a Gametracker bug.

We will never publicly divulge the email address of a registered user.
We will never privately divulge the email address of a registered user.

If you own the email address, you may request a password reset at login.

I created this account a long time ago and now I wanted to change the description and delete the clan because I am going to a different starter network and typed all my emails (I have three) that I used and none is assigned to an account which is not possible. I would love to ask you to reset your password and the email address can be defeated so that I know the beginning of at least user***games***@gmail.com

I don't think you understand how internet security works.
If you don't know the email address of the user account, how could you possibly check for an email from that account?
If you have such a large number of email accounts that you can not keep track of them, my advice to you would be to keep a record somewhere.

Other than that I can only refer you to my previous response, with particular emphasis on the word 'never'.

Sorry, we can not help you.
