The standard Drupal contact page is linked to from the navigation menu. I filled in the main categories, sales, support and info. However, I think our old web site Contact page is superior. Addresses etc could be added to the Drupal version but we might as well just copy the old page over and use that. Also, I prefer to send email from my usual client rather than a form.
Providing a form for the email would be helpful if a regular mail client wasn't available. So perhaps a link to the Drupal Contact form should be added to the copy of the old Contact page?
