Great to have you here. Hope to see you around the forum.
I should point out that this is your personal visitor message area where visitors can leave a message for 'you'. If you respond in here, you are likely the only one that will see it unless someone like me comes along to say 'HI' and happens to notice it.
If you click on 'View Conversation' then respond there, your reply will go to that members personal visitor message area. In this case, I doubt that Shane knows you tried to respond to him.
