You've found a member whose content is just your cup of tea, why not follow them and notified of their posts!
Following:
Navigate to the profile of the member who you want to follow and press follow – it's a simple as that!
(You will need to have push notifications enabled on your own profile to use this feature)
Unfollowing:
If you later decide that you no longer want to follow a member, then simply navigate back to their profile and tap following. This will instantly remove your follow.
Following is different to connecting & messaging – you can learn more about this here.
