Ever find a picture with four smaller pictures and wonder why. Simple its a GROUP. Most FACEBOOK users will check the box to remove "GROUPS". to bring it back, click ABOUT and then MORE. On the popups click on GROUPS. Now when you perform a search say on REUNION, Military unit, LDS groups, or a thousands of others with city names. But note the pictures with four pictures, that is a group. When you find a group, you mostly will have to ask to join. Once in you can Post a message and or picture(s). If your just looking at a group and not a private group you can read and view posted picture(s) and stay in direct contact with old friends once you join or create your own group. Enjoy and stay safe while in cyberspace.
