There was an email on the 24th of May, 2015.
I certainly did not get it, and I asked a few people from whom nobody got it either.
It came from the standard email address where I normally receive messages from, regarding new PMs and such. I suggest you either check if you receive emails at all from the forum (settings etc.) or change the email address. It's good to stay up-to-date in such situations.
Although, indeed there was a message in the forum header as well.
