How-To Geek

Hi
I was looking up ways to add emoticons to a comment I was posting in Facebook. This site I found told me to use the alt key and a number. I did that, and because I was using my laptop which doesn't have a number keypad on the right of the keyboard, it didn't work. I finally figured out how to do it (also hitting the fn key and a number in a square on the regular alpha keys). However, I noticed some of my friends comments on my profile page were gone. When I was first using just the alt key and a number at the top of my keyboard, Facebook kept taking to my Friends page. So I am afraid that in the process, FB deleted some of my friends' comments. Is there any way to bring them back? I'm bummed because it is my b-day, and the comments that disappeared are some neat b-day comments. :-( (no alt key used here! lol) Please help.
