Hello Robyn, thanks for accepting my invite, nice to meet you. have a great Sunday.
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, which is easy to make friends, you can ask), 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, discussion boards, making friends to network with plus so much more. If you have any questions just leave a comment on either my wall or any of your friends walls and we will help you.
