We don't have a standard entry form available, but you can create your own using this one as a template and cloning it: British Open [1]
Clicking on the Submit button at the bottom will send an email to the address in value in the <input type="hidden" name="recipient" value="?@?.uk" /> line.
You must also change the URL on the <input type="hidden" name="return_link_url" value="/britishopen/form.html" /> line.
You will undoubtedly need to make other changes and don't forget to test it before announcing it publicly!
