Following is like subscribing to another member; you'll receive notifications of their activity in public areas.
How do I follow another member?
To follow a member, visit their profile page and click the "Follow Member" link under their avatar. You will be able to "unfollow" someone in the same place.
What will I be notified about?
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 "Block Member." This will also prevent them from sending you private messages and will collapse their posts when you view the forums, so use this carefully! Also note that you cannot block site administrators and moderators.
