I tried creating a ChefSteps account with an email address of the following format: "myname+something@example.com". When I hit next on the keyboard, indicating that I wanted to create my account, I got forwarded to the login page. Then when I tried to login with that supposedly "created" account, it says it didn't exist and I didn't receive any confirmation email. When doing the same thing with the email of the format "myname@example.com" everything worked out as it was supposed to and it forwarded me to setting me up with my Joule.
