Everybody knows what Facebook is, and with about 1 billion users across the world, it's easy to see. Still, just because you know what Facebook is, it doesn't mean that you know how to properly use the service, and take full advantage of everything that is has to offer. That includes people who have already been on Facebook for years and still don't really know what they're doing. The truth is that most of us are in need of Facebook lessons, whether we want to admit it or not.

Some people may need lessons on the website simply to learn how to have more fun, and use more of the features. For example, do you know how to tag photos that you post? Do you know how to post photos directly when you take them from your camera? Do you know how to include other people's names as a link automatically on your status updates? These are all relatively simple features that may seem confusing until you actually learn how to do them properly through a quick tutorial.

In addition, you may want to begin using new capabilities, like the different groups you can break your friends down in, so you can read only their updates, and send your updates only to select people. From there, increasing your privacy settings or changing your notification settings may be a concern.

Both of these are priorities, but few people know how to take action the right way. Privacy is really of the utmost importance on Facebook, and you need to know why that's the case, and how to change the way you interact with the service so only the people you trust can gain access to your information, your photos and more.

You might also need lessons to help you get adjusted to the new Timeline style of profiles and pages. Adjusting what other people can see, what your main and then your smaller images are, where your information goes and more is all different with Timeline, so you'll need to see how to jump in.

Now that you know why you need Facebook lessons, you may be wondering how you can actually go about finding them. The good news is that there are many different tutorials and guides available online.

The majority of these services and websites are completely free to use, so there's no risk or obligation. In addition, they'll be up to date with all of the latest changes to Facebook, as opposed to printed books which you have to pay for which are out of date the second you buy them. Online lessons will also typically be easier to work with and navigate, so you can get started easily, and without any hassle.

Whether you want to learn how to have more fun on Facebook, or you want to learn how to protect yourself more on the social networking service, using appropriate lessons is certainly the way to go.
