The new feature allow users to get notifications whenever another Facebook user uses the social-networking site to update their status or share photos with friends. The new 'subscribe to' feature helps Facebook users to select which friends or family members they want to receive alerts from whenever there is any activity on their Facebook profile.
"We are testing this feature with a small percentage of users. It lets people subscribe to friends and pages to receive notifications whenever the person they"ve subscribed to updates their status or posts new content, such as photos, videos, links, or notes," said Facebook in a statement.
The launch of the new feature to the users is not yet confirmed.
