If you need to, I can atest to its validity if given a vouch copy. I have done this before quite a few times already for other different services.
I will PM you now.
I have followed the method so far and it *seems* to be legit albeit I cannot fully confirm it yet. The resources provided by the OP are quite helpful and make it fairly easy. Please wait until later, since there is some downtime to obtain the addresses. Once I do I will post a full review.
EDIT: I haven't had a chance to check if it worked, but I will update as soon as I get home.
