I've gotten MANY comments and complaints from various users about them trying to hide their email address, but it's apparently not working. If you go into your profile and check the hide email box, then save, it will indeed hide your email as requested. However, you will ALWAYS be able to see your own email address, so if you check, it may appear like your action didn't work. This somewhat confusing behavior is just how this forum software works, but rest assured if you set your email to hidden, it will be.
