I got this and renewed yesterday as it said what to expect and who they were using and it tallied. Mine expired and the renewal wouldn't work. I emailed them about it but didn't get a response.
It was dead easy. Like paying for something with Paypal but you can use a card, and my confirmation came by email straight away. Hoping they remind us when they are due to expire in future and I didn't last year!
I think it works well, and told them. Then got an email back from a named person thanking me for my feedback so all legit. Renew/join away!
