As @Tenshadesandme said, it sounds like you’re doing it correctly. Once you’ve submitted a review, you usually get an email asking you to confirm your username (this usually goes to my junk email so check your spam!). Your review will then be checked and hopefully approved (they won’t modererate your review for being critical but they do check that it’s not inappropriately graphic or offensive). It should then appear on the website. It might be taking a bit longer than usual at the moment if lots of staff are on holiday.
The reviews don’t link to the forum so if you’d like to add your review to the forum, you can copy it into this thread from the website.
