Facebook is rolling out a new feature they are calling graph search. To access the graph search go to the lock icon and click it. The graph search allows users to enter a phrase such as, “My friends who like the Hangover.” It will then scan all your friends and present the results. You can use it to show results based on location, interests, gender and other information in your profile.
Yeeaah, you do not want to get tagged in this picture!
It can also be used to find pictures of you that were previously much harder to find. To review your photos go to your profile and then click on “Activity Log.” Click on “Photos” and then “Photos of You.” A bunch of pictures, of you, should appear in chronological order. Search through the list and make sure that any pictures you see are picture’s you will be comfortable with. If not, then you can untag yourself. Just click on the picture and options will pop up. There will be an option to untag yourself, which will make it unsearchable, and another option to remove the picture entirely. You will need whoever posted the picture to remove it if you want it gone entirely.
