This button allows you to Follow or Unfollow the Challenge's creator! It's exactly the same thing as the 'Follow' button that appears on their user page!
To follow someone, simply click on the 'Follow' button and they will be added to your 'Following' list, which you can access HERE.
To unfollow someone, simply click the button once more and they will be removed from your 'Following' list.
If you have any questions, please send an email to firstname.lastname@example.org and we will get back to you as soon as possible.
