Cardano forum not working properly: changing email not possible

Hi,
I want to change my cardano forum email address. Unfortunatelly, I do not get a confirmation mail (Gmail) and therefore cannot change may email.

I tried to register a new account but do not get any email to confirm my new profile.

Seems like the forum system does not send any emails.

PS: I tried to delete my account but I am missing a delete account button.
