Normally, you start a "conversation" with the person you want to talk with privately. You pull up his / her profile and you'll see a link "Start a Conversation".
This way you're not posting an email address here in the forums and ending up on someone's spam server.
I'll see if I can bring the instructions to work tomorrow and scan them for you. I started a conversation with you already so you can send me the email address to which you want me to send the instructions.
