    Hello, Ms. Whittaker. A belated happy new year to you. 🎄🎉

    Link #1 is broken.

      Happy New Year Mystery Man! I can always count on you to keep me honest – link has been updated :). I hope you’re doing well!

        I hate to be a pest but, regrettably, it is still broken.

        I believe the correct number at the end of the link is 245, not 8090.

          You’re not a pest at all. I pulled a different link (moving too fast!). Now it’s right. So sorry!
