First, this topic belongs in the "Newcomers Forum" actually... ;)
It's very easy killerkingz... when you visit someone's profile, it has a green Add Friend button in the right top corner of his/her about section. Click that and you added him/her to your friends list! ;)
If you still want some more information about this subject, you can read all about it in this thread in the Newcomers Forum! =)
