Hi Gillian,
Re: "I have messaged Peter on this site but I came across it by pure chance and i am not entirely sure how it operates".

When you post a message it appears on the board, and also goes to the private email address of the person whose message you are answering (if they have chosen this option). So this reply should go to your email address.
I'm glad that both Peter and K have now answered you. Remember that people using the message board live in different time zones.
