change of address of ABRSM...sigh!!! :(

[karenfong716]

I had an exam on ABRSM theory exam 2010 October, but after that exam about one month, I moved to another address.

I have moved but I do not know how to change my address, I am a candidate and also a applicant. My friends received certificates but I do not have,they received them a few days ago! I want to know how to change my address.
I am going to receive a piano exam that I had examined last year August. If I don't change my address, I afraid that I cannot receive that certificate

I really need this help! Thank you very much!
