@kaype, there is indeed.

You can test for the user belonging to a specific usergroup by adding a little bit to the IF block, like so. :>

PHP Code:

if (!$post['signature'])
{
  if (is_member_of($this->post, $my_usergroup_here))
  {
    $this->post['signature'] = 'THIS IS A DEFAULT USERGROUP SIGGY!';
  }
  else
  {
    $this->post['signature'] = 'THIS IS A DEFAULT SIGGY!';
  }
} 


@Evertonized, I made a booboo in my code. (Forgive me, it was before I went to bed. XD) There should only be a SINGLE equal sign for assignment.

I had you putting,
$this->post['signature'] == 'THIS IS A DEFAULT SIGGY!';

It should be,
$this->post['signature'] = 'THIS IS A DEFAULT SIGGY!';
