How do I change my account info?

I used search and looked in various non-GWG places, but I'm terrible at looking for anything so please forgive me ><

Say I moved to a new house some hundred miles away from my current residence. How would I change this information in Guild Wars? You are asked your address when you create an account, so how would you update this info?

And this next part is a stretch but, what if you had your name changed legally? Would you be able to change the info in Guild Wars? If so, how?

Thanks in advance for any help.

Login and click the Edit Account button.

kinda annoying as it now directs you to the ncsoft master account page and you can no longer use !@#$%^&*() in your passwords
