That is blatantly not true.

<input type="text" name="txt1" />
<input type="submit" name="submit" value="Send" />
However, there are disadvantages to using mailto: including
1) Some older browsers don't support it
2) It requires the user to have an email client program installed on their computer and to have it configured to work with a POP mail account
3) The contents of the email are not encrypted for privacy.
