In this video I show you how to create a facebook group. From the homepage, you can click on the "groups" link on the left hand side. One this page, you can manage all of your facebook groups and see recommendations.
On the upper right hand corner you can click "create group" to make your own.

It is as easy as that! Good luck growing your facebook group and inviting people to join your facebook group! Leave a comment if you have any questions!
