Where I see the address linked to my account? I think I never added added a address to my signature. But t I sent a few PM with my address.
I checked and the account has these two addresses in its post history:

1VFrAtRqkq5vPXzMfS6f8fdZhmE3ejdvz
It would be good for your case if you could sign messages with them.
