can i change my email address for gw?

Hi everyone
I have been away from gw for bout 6mnths aside from the gwen preview wknd and have come to a problem of sorts as im looking at moving house in the next 6wks and where im going already has an internet connection so I wont be able to keep my current email address I use for things such as gw I realise that in the past u couldn’t change the email address that the game was registered on but was wondering if such an option has been added in the last 6mnths or so as I cant seem to find an option for it anywhere aside from the ncsoft account which I have changed already to my new address.
The main thing I am worried about is while I can still play the game if someone else gets that email address and I perches something from the online shop im guessing the recept sent to the email address will have the billing details inc the credit card details like most other games (I haven’t bought anything from the gw store as of yet so I cant confirm this myself).
Anyways im sure that’s more then enough details ect of my problem lol any help on this issue would be greatly appreciated.
Cheers loony

Emails don't get sent to the Guild Wars username, only to the PlayNC account email address which you say you have already changed.

There isn't anything to worry about. The worst that can happen is someone with your old email address tries to create a Guild Wars account with that address and can't. As long as your password is good they won't be able to guess it.

In other words, you can't change the account user name, but you can change the email address on the ncsoft account that they use to contact you.
