Also answers the question I was going to ask
If you mean by contacting me direct you can't as such, at least not from my website.
When I started up with my website I had an e-mail link but soon dropped it when I started getting mail from all the weirdos in the world.
I think there is enough scope here on these forums for that, plus it also means that others can take part in the debate.
If push comes to shove and you do want to get in touch privately then you can use the personal messages facility at the top of the page.
I hope that answers your question.
