Facebook help- embarrassed to ask my kids?

[Stefan]

1. On the top blue margin,next to your fb name,press the white triangle,then account settings.
In there you will immediately find your name and by clicking on it,you'll change it.
2. It must be one of these two things: a) the comment has been deleted b) the facebook server didn't receive your comment. Refresh the page,type in your comment and press enter.
3. Well,that's what sharing does. It shares that post,you can see it as well as everyone,there's nothing wrong with your post showing on your wall.
4. Not to lie to you,but i think that adding previous places you've lived in is impossible and also things you've done in the past.

hope I helped
