advice changing e-mail address on gc

I am due to change over to bt tommorow when is the best time to change my e-mail address on gc should i wait until i am up and running on bt broadband as in my profile it states that an automatic change of your password by the system is sent to your e-mail address. :confused:

 

Yes, wait till you've got an e-mail addy for the system to reply to! It won't really matter much till then.
