I live in the Uk. I have a .co.uk email address. Tonight I get a “Thanks for Choosing NOOK” email for registering my new device
Considering they dumped UK customers a few years ago I very much doubt i’ve managed to register a new Nook any time recently
I did have a Nook registered before they closed the UK store, I can only assume some bright sprak in IT has reactivated some old accounts.
