This first example hides the "from" fields from the user. (This example
uses MY coolservlets.com email address so PLEASE be resonsible who you send
emails to!)
Second example:
This example is similiar to the first one but here you can specify who the email
is from.
Third example:
This is probably what you would do if you were using this servlet for some kind
of user feedback page.
Fourth example:
This servlet shows nearly all of the fields. Try leaving one of the required fields
blank and submit the email. You can also try changing the colors specified below (they
define what colors are used in the response page).
