title: How do I let to browser to remember the input of the text area
body: <p>In case a user forgets to enter an input area or enters an invalid code, and then comes back to the page where the users was filling a form, then he/she will face that his/her textarea is empty. And won't want to fill it again. I want from the browser to remember what was written in it. How I'll do that?</p>
  
  <pre><code>&lt;textarea cols="60" name="event" rows="20"&gt;&lt;/textarea&gt;
  </code></pre>
  
  <p>(Yes I can validate with javascript the email-name etc areas before the send button but I was unable to validate the captcha by a javasript)</p>
