title: Automating facebook messages on facebook if certain conditions are available
body: <p>I want to do add a feature in my facebook page messages:<br />
  it's to remind page followers about something at a certain time and this &quot;something&quot; depends on what they choose or if they are online or no:<br />
  <strong>for example:</strong></p>
  <ul>
  <li>If a user sends &quot;A&quot; to page messages it automatically sends him &quot;a&quot; at
  2:00 everyday.</li>
  <li>If he typed in &quot;B&quot; it automatically sends him &quot;b&quot; at 4:00 every day.</li>
  </ul>
  <p><strong>so my question is:</strong> is there a website or a tool that lets me do this, or should i code it using something like selenium</p>
