Follow Function of Actors/Actresses???

I have read about and seen the follow function but it seems to have otherwise disappeared and lost functionality from the site...? Anyone know what is going on? I am discovering a lot of new actors and actresses on here and can't always remember all their names so early on so it would be nice to be able to follow them or something to be able to refer back to... Or are there alternative options I can use? Thanks

I'll do that thanks
