I'm staking a new address now, and although I can still sign a message from the old address, I don't want to rely on it anymore.

Unstaking old addy
-----BEGIN BITCOIN SIGNED MESSAGE-----
In June, 2016, I accidentally copied the private key for 1foreverDArUNEX2gVD26vautcx3b8zTZ in my Google search bar. That's been bugging me ever since. It still holds a small balance (), which isn't what I worry about (and I still use it for tips).
I've downloaded my data from Google, and it confirms Google still knows the private key. It's not something I worry about that much, but it's a loose end to tie up.
Today is April 18, 2019. I, LoyceV, am "unstaking" address 1foreverDArUNEX2gVD26vautcx3b8zTZ at Bitcointalk.org and staking new address 1LoyceVGjMmUj6Na79M9Ju8N52KXkbKMQE.
