Why the hell can't I change my email address?

Minutes after I registered this account I got a message from the provider of the email address I used that they are going to be no longer providing email in a couple of weeks.

I dont want to be left with an account with an address I no longer have access to.

On most sensible systems you simply go account details and change your email address, not here though!

All I can do here is change the country I live in. Hello? I'm more likely to need to change my email address than inform you (for no obvious or stated reason) the country I live in has changed. What monkey "designed" this system?

*bump*

I want to change my email address, too. my one does not exist any more.

same here. i registered for the demo, hence used a temp address. now that i bought the game, i want to switch to a real address.

Also want to change my email address, cause the registered one is not valid any more.
It seems gamesas.com is sharing the account with GameSpy and IGN.com, otherwise I can't explain why my GameSpy account is working on gamesas.com
Although I have recently changed the email on GameSpy gamesas seems not to accept the changes.
