Click the Login Link in the top right corner of the page
You will see a screen that give you 2 options: Send me a Login Link and Login with Gmail
If you use Gmail, then the fastest way to login is to select Login with Gmail. This will bring you to the Gmail Login page where you can select your account. If you are already logged in to your Gmail account, it will automatically log you in to Curling I/O.
If you don't have a Gmail account, then choose Send me a Login Link. You will immediately be sent an e-mail with a login link. When you click that link, you will be logged into Curling I/O.
If for some reason you can't click the link, you can instead copy the "Token" from the e-mail and paste it into the "Token" field on the Curling I/O Login page.
