title: Moodle 2.8.5+:How to set new block access rules?
body: <p>I am developing a new block. I added it's instance to the page, but there are two problems: </p>
  
  <ol>
  <li>after turn editing off it will disappear. </li>
  <li>after logging out as a user it will disappear. I think the problem is related to db/access.php</li>
  </ol>
  
  <p>I like the block to be sticky an shown to every body: users, guests, etc. So how I can solve this problem?</p>
