Some suggestins to make the module work better.

I'm glad the bug fixes are now in place and everything appears to be working as design. Here are some suggestions to make this module more usuable.

Enable private messaging as default
At the moment the way the module works is that it relies on user intervention to enable private messaging. If they don't enable it they won't see other members "write to author" links. I assume this is by design but that effectively hides the usefullness of the entire module.

After all most members rarely go back into their edit profiles so they'll miss the new features. Have it turned on by default for each member and then they can decide (if the admin see's fit) to have it disabled.

A admin toggle switch allowing whether the members can turn on or off private messaging in their own accounts would be handy.

Write to author visiable to all members
Everyone who is a registered member should see the "write to author" link if they are logged in regardless of whether their own preferance is to not receieve private messages. Currently if i have private messaging available and they do not they won't see my link by design.

Annon users should not for obvious reasons.

Pop Up Notifications
As it is the why a new message is handled is easily missed. A simple javascript popup box when a new message has arrived and is unread would make sure the member never misses his message.

Heres a fragment of code that may help. Its from a subdreamer notification box that does the same thing. The javascript maybe usefull here.

if(strlen($pmpopupurl) > 0)
  {
    echo '<script type="text/javascript">
<!--
  function NotifyMsg()
  {
    if (confirm("'.$language['new_priv_msg'].'\r\n\r\n'.$language['sender'].' ' . $pmfromuser .'\r\n'.$language['title'].' \''.$pmtitle.'\'\r\n\r\n'.$language['click_ok'].'"))
    {
      // Output when OK is clicked
      if (confirm("'.$language['open_msg'].'"))
      {
        var winobj = window.open("'.$pmpopupurl.'", "popup", "menubar=yes,scrollbars=yes,toolbar=yes,location=yes,directories=yes,resizable=yes,top=50,left=50");
        if (winobj == null)
        {
            alert("Couldn\'t open the new window. Are you using a Popup Blocker?");
        }
      }
      else
      {
        window.location = "'.$pmpopupurl.'";
      }
    }
  }
  
  window.onload = NotifyMsg;
//-->
</script>';
  }  

The ability to download
The ability to download receieved messages for off site archive is always a very handy feature. They can be downloaded as simple .txt if that suffices.
