A question about facebook privacy?

[Yahoo mania]

Yes at the Bottom Right of your post you should see a globe or two shadows on men .
When you hover your mouse next to the icon a inverted triangle should appear click on it and set the privacy settings to friends only
(OR)
If you have the new layout Click on the lock shaped icon next to the wheel and Click on the arrow nest to WHO CAN SEE MY POSTS
Select Friends under who can see my future posts

NOTE:When you tag a friend in a post or a pic
(OR)
post a pic or anything on his wall .He controls who sees the posts . His Friends or Friends of Friends will be able to see the posts and there is no way to stop that.
Posting on a facebook page is always Public and there is no way to stop that also

Sorry ,But I hope I helped
