I have a 'follow' feature on my site and I am unsure of how to handle it for users that are not logged-in.
I currently show the button for all users, and then if the user clicks the button but is not logged-in, a message is displayed explaining this feature is for members only.
I would like the button there so that non members know that there actually is a follow feature and therefore would hopefully be encouraged to sign up.
I am however unsure if this seems like the wrong way to go.
What is the most effective method to handle this?
