Is there a setting to add Facebook, twitter , Instagram profile links?

Thank you for the tip that is interesting however I was referring to the single facebook or twitter link for my forum. so maybe at the top next to search there is a facebook twitter icon etc. Similar to the way it is here in the top right http://www.flaquarium.org/ I understand I can accomplish this with custom css etc but I just wanted to make sure there wasn’t a social option already baked in.
