I don’t know if this answers your question, but this is what I have posted on my FB page:
PLEASE DO THIS FOR ME .THANK YOU .To all my FB friends, I want to stay PRIVATELY connected with you. However, with the recent changes in FB, the public can now see activities on any wall. This happens when our friends hit “like” or “comment”, automatically, their friends would see our posts too. Unfortunately, we cannot change this setting by ourselves because Facebook has configured it this way.
So I need your help. Only you can do this for me. PLEASE place your mouse over my name above (do not click), a window will appear, now move the mouse on “FRIENDS” (also without clicking), then down to “Settings”, click here and a list will appear. REMOVE the CHECK on “COMMENTS & LIKE” by clicking on it. By doing this, my activity amongst my friends and my family will no longer become public. Many thanks! Paste this on your wall so your contacts would follow suit too, that is, if you care about your privacy! Thanks
You might want to create a facebook “Just for Work” and keep the other just for family/friends. Never the twain shall meet!
