Hi @jcrodriguez! Thank you very much for your welcome.
Indeed, the griselt account is mine but I stopped using it for a long time. A few days ago I decided to activate my publications and I realized that my account had been jacked. I tried to recover it, but it was impossible.
I appreciate if you can advise me on what to do to close my old account, taking into account that I now have a new one.
Thanks for your recommendations, I will check the newbie guide.
