Mailto function

After doing some investigation I found that you can actually cc and bcc mail recipients using the simple HTML mailto function. This can be done by using the following syntax mailto:test@test.com?cc=test@test.com?bcc=test@test.com?subject=This is a test subject. This is something that might be useful to some people as I always believed that you could only use the to field and that the cc and bcc were not able to be accessed.
