In order to register with the channel and create a username for yourself, first locate and click the tab or button named "Register" (or similar). You may first need to click "Login" (or similar), then "Register". This takes you to a registration page. Please note that registering for email alerts is a separate operation from registering with the channel. Registering for email alerts only puts your address on the mailing list - it does not create a user account, which you will need to make a purchase.
Fill out the form per the field labels. Ensure the username you select is unique and is at least six (6) characters long. In the two name fields, enter your first name in the first field and last name in the second field. You will need to type your email address and password twice each for confirmation. If you see a red asterix next to any field, it means there is a discrepancy. Please adjust.
Finally, enter a password hint then click "Proceed" (or similar).
Once you submit your registration details, the information in the tab frame will be replaced with another tab, confirming your details and showing your purchases so far (which should be "none").
