Facebook now has over 1 billion active users, but a large minority of these people don't know the full extent of things they can do on Facebook to maximise their experience.
Check out these 10 features of Facebook that you never knew about before.
1. The Facebook Inbox You Didn't Know You Had
Depending on how long you've had Facebook, you're going to have a secret inbox full of unread messages you never knew you had. To see this inbox go to "messages" in the top left column (or conversely, just click on the messages icon up at the top). By default, you'll find yourself in your main Inbox where you find all the messages you've received from your connections. However, if you look directly to the right of your "Inbox" at the top, you'll find the "Other" folder.
This "Other" folder is full of messages from people you aren't connected to on Facebook. A lot of it isn't important, but you never know what you'll find in there.
2. See Where You're Logged In To Facebook
If you've ever left your Facebook logged in somewhere else you know how much of a pain it is trying find out where and get yourself logged out of there.
First, go to your settings page. Under the Security folder, you'll see the link "Where You're Logged In." Here you will find all your active Facebook log-ins from both desktop or mobile. You'll also be able to log out of these sessions if you wish.
3. Turn Facebook Upside Down Or Into Pirate Language
If for any reason you've ever wanted to turn your Facebook interface upside down, or have it turn the language into 'pirate language' then today is your lucky day. Alternatively, if it's not really your thing then it's always a good way to prank someone.
Go to General Account Settings > Language, and you can change your settings to either "English (Pirate)" or "English (Upside Down)."
4. Add Interest Lists
Unless you've had a good clear out, your Facebook timeline is going to be filled with a load of old junk that you don't particularly care about. Well now you can condense all the stuff you want to see into an interest list.
To access interest lists, scroll down to the "Interests" link in the left column, hover over the header and click on "more." On the next page, click the "+Add Interests" button and you will have the option to search and follow other publicly available interest lists or create your own.
5. Detail Your Relationship
If you're in a relationship (or at least in a realationship on Facebook), then you can see a detailed FB history between you and your significant other.
Head to facebook.com/us to check it out. If you're not in a relationship and you hit the link then it'll just go to your profile because Facebook thinks you're in love with yourself.
6. Transfer Files Over Facebook
This isn't so uncommon but it's good to know if you already don't. You can transfer files to anyone of Facebook by clicking on the little gear icon at the top of a Facebook chat window, then hitting 'add files'.
7. Choose Who Controls Your Account After You Pass Away
Everyone on Facebook will most likely die one day, so Facebook needed to integrate a function to deal with accounts of people that have passed away. In comes Legacy Contact, this lets you choose someone who can control your Facebook account after you pass on.
This contact will have the ability to write posts, deal with friend requests, or update profile photo's. Quite creepy really.
8. Save Posts for Later
If you're on Facebook a lot then you're always coming across articles which look so interesting, but you just don't have the time to read them. Well Facebook has a handy save-for-later function so you can store them instead of just letting them go.
If there's anything you want to save for later, click the little arrow in the top-right of any post. Then click the Save "[name of story]" button from the pull-down. Whatever you've saved then gets stored in a folder (named 'Saved') down the left side of your Facebook homepage. This folder won't appear until you've actually saved something.
10. Turn Off Game Requests Notifications
Finally Facebook have implemented the ability to turn off game request notifications, easily one of the most annoying things about using Facebook.
To turn them off on mobile go to Settings>Account Settings>Apps>Platform, then hit No where it says 'Game Invitations and App Notifications'.
