New account activation not possible

Dear Suppot,

I created a personal account on ProjeQtOr.org on 2021, March 7, and received a mail containing an activation link.
This link does not work : it open an error page "403 Code de vérification non trouvé".

Moreover, the indicated connection ID is not the good one. I certainly made an error while creating.
Is it possible to cancel this account and let me create it again ?

Thanks a lot.
