Ok...
Is this what I have to send?

I would like to claim this record as well. As you can clearly see, I have signed the message stating my ownership. I... uh.... just logged into my other account, or something.

In all seriousness, though, congrats on the find!
Well sign it something like "[real name] - [username] on btctalk".
So people can assign a real person to the record and we know who you are on here
Just suggesting.
