Now What? Facebook is a social network, so you want to invite some friends to view your page. One way to do this is to search your High School year under find friends. You'll be surprised at how many people you will find. Once you chose a person, you will need to send a friend request to them. Once they accept it, they are privy to your facebook page and all that is posted there, including comments made by other friends. However, you can not view a persons page unless they accept your friend request. For example, if Sue and Mary are friends and Sue is also a friend of John, then Mary can read the posts that John leaves for Sue, but Mary can not see John's profile or photos unless she is friends with him as well.
