I've just seen this on their Facebook page, from 25th Feb (I don't check their page that often!)
We're starting a new Findmypast community and if you're seeing this post we'd love you to join. Interested in exclusive content, sneak peeks at upcoming features, inside information from the world's leading genealogists, and much more (all for free)?

If they are opening it to anyone who emails them, I don't know why they couldn't email everyone who is registered with them to tell them about it instead of only a few? (I didn't get an email.) Have emailed them.
