After digging around, I found an address linked to my Coinbase account:
14qkrG9VbDjjoqb7Kyqc9WRkJYqRfWzwf7
Here is the message and signature (Coinbase allows you to sign messages on their site, sweet!)
Here is the message I wrote:
"I am the Real YURIYGEORGE. Please reset my account password and e-mail address. January 31st, 2017."
And the Signature:

From this original post coming from my real account "yuriygeorge" here:
where I advertised my old-never-went-anywhere Bitcoin Research Blog:
https://bitcointalk.org/index.php?topic=244288.msg2590335#msg2590335If you go there and follow to the link to my old blog (yurirush is the blog admin name, similar to yuriygeorge):
https://bitcoinresearch.wordpress.com/2013/06/27/coinbase-rights-to-own-versus-rights-to-control-your-bitcoins/This was like the first post I ever made on the yuriygeorge account btw.
You'll see there is a post I wrote there (yurirush) the user name I used.
You'll see my BTC address above (14qkrG9VbDjjoqb7Kyqc9WRkJYqRfWzwf7).
Now, luckily, I sign into my Coinbase account, and low and behold, this address is still in the system from 3 years ago.
Is this good enough? I sure hope so.
