Our WebMD site registration is separate from WebMD newsletter subscription. 

To fully register with WebMD, complete the online registration form at: https://member.webmd.com/register.aspx. Once you complete the registration process, you will receive an email asking you to confirm your email address. After your email address is confirmed, your newsletter profile will merge with your WebMD registration.

You then will be able to log in and join the interactive areas, like WebMD Health Exchange and fully use all of our tools.
