I have a website with a lot of furniture products. Each node page has a link to "ask for more info" that opens the sitewide contact form. When I receive the e-mail message, I need to know to which product (node) the request refers to, because many people forget to say it. So I need to pass node url, title or nid to the form in order to insert it automatically in the sent contact e-mail.
Thank you very much
