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