In FamilySearch (not the community) go to your account settings (upper right on your user id) and look or the Contact tab and you will see an option to enable "relationship viewng"

There are two ways that I know of:
One, as 'Dennis' has already suggested is through your "Settings", under the "Contact" 'Tab', in "FamilySearch".
The other is when you select the "Contact Name" of a User/Patron who has contributed details to a record.
I hope this helps.
