This'll let you change the email on an account even if you don't know the secret question or have access to the original account.
(Say, if it's old and you forgot, or, err, whatever)
1) Go to starwarsgalaxies.com
2) Log into account.
3) Go to "Support Site" on the top right and click help.
4) Just select anything for the search, doesn't matter... click search
5) Click "Chat Support"
6) It'll ask you to verify your email, type the new email address you wanna use, click okay or confirm (whatever the button is)
7) Go to your email and confirm it with the link
Cancel the chat
9) Go back to your account, and after a few mins your email will update
Not a huge deal, but it's handy. I figure this'll work for any SOE account.
