How can I change my mail address in bugzilla.

Hi, I reported a bug to bugzilla and noticed that my mail address is no longer valid. I could log in, but any mail will not reach me. https://bugzilla.opensuse.org/buglist.cgi?quicksearch=darktable&list_id=13661607 The page doesn't have or hides very successfully the location where I could change my email address. "Preferences" point to "Account Information" but wants too much information. Alternatively I could cancel my account and open a new one. But where? Peter
