Following is like subscribing to another member; you'll receive alerts of their activity in public areas.
How do I follow another member?
To follow a member, visit their profile page and click the "Follow" link to the right of their avatar. You will be able to "Unfollow" someone in the same place.
When will I be alerted?
When following another member, you'll be notified about many of the same things that appear in their activity feed: replying to threads, writing reviews, and other actions they take around the site.
Can I stop someone from following me?
If you're concerned about a member who's following you, visit their profile page and click "Ignore." This will prevent them from sending you private messages as well as hide their posts and quotes when you view the forums, so use this carefully! Also note that you cannot ignore site administrators and moderators.
