I can't find this option anywhere

Did you look in
Main account page?
Ok have a problem with this, dunno what I'm doing wrong, but:
I try to edit my country in Main account page. In FF 3.0.3 in the edit-form username is then written in the email-field and the 1st password is filled out, but I changed country anyway and got an "Invalid email-address"-message. Duh!
So wrote the correct username in the correct username-field and email-address in the correct field. Didn't bother with password since I didn't wanna change it... then got password-error-message. Ok!
Filled out both password-fields with correct password, then got a red cross at username! One last try in FF 3.0.3 emptying all pre-filled fields, then get "No name entered" and "Invalid email-address". Hmm, perhaps a problem with FF then, I thought?
Very, very reluctantly opened IE 7.0.5730.13 and tried the same. Everything is empty except country and country IPC, so I change country and hit "save" and... nothing happens!
I did change country in all "my" projects (except CPDN, database down ATM), so it shouldn't really matter if as stated the majority rules

But anyways wanna report this as a possible bug :/
