Hello Charlie ; nice to meet you, thanks for accepting my invite.
If you want to respond to someone that made a comment on your wall, or make a comment on their wall ( if you are friends with them) just click on that persons picture or name and it will take you to their page. Then scroll down to their wall write something and then click submit. There is alot of information and things to do here, like joining groups, discussion boards, making friends plus so much more, that can possibly help you find that govt / fed job. The more friends that you have the more you can network. If you have any questions just leave a comment on my wall or any of your friends walls and we will help you.
