I notice this link of code returns nothing if the user is anonymous...

No, its the user ID of the blogger.

Sorry for being unclear. I am usering the "Blogger" module to help me create a resume book for a class. Of course, I need to modify things. For example, I want it to say "Resumes" not "Bloggers" in the titles. That wasn't too bad.

Here is the code for the function that outputs the list. This is where the issue lies:

function blogger_page_list() 
{    
  $maxdisp  = 1000;	
  $shownum  = variable_get("blogger_shownum", 0);  
  $blogger_order  = variable_get("blogger_order", 0);
  $blogger_exclude = variable_get("blogger_exclude", "'0'");
   
  $blogger_case   = variable_get("blogger_case", 0); 
  $blogger_avatar = variable_get("blogger_avatar", 0); 
  $blogger_avatar_width = variable_get("blogger_avatar_width", 0);
  $blogger_avatar_height = variable_get("blogger_avatar_height", 0);
  
  $sql_counts = " SELECT DISTINCT (u.name)"
	           ." FROM {users} u"
	           ." INNER JOIN {node} n ON n.uid=u.uid"
	           ." WHERE u.name<>'' AND n.type='blog' AND n.status=1"
		       ;
  $dse_sql_counts = db_query($sql_counts);
  $cnt_sql_counts = db_num_rows($dse_sql_counts);
  $sql_counts = "SELECT $cnt_sql_counts";
	
  $sql = " SELECT n.uid, u.name, count(u.name) AS numitems, u.picture, n.title "
      ." FROM {node} n "
      ." INNER JOIN {users} u ON u.uid = n.uid "
	  ." WHERE n.type = 'blog' AND n.status=1 "
	  ." and n.uid not in ($blogger_exclude) "
	  ." GROUP BY n.uid"
	  .($blogger_order<>0 ? " ORDER BY " : "")
	  .($blogger_order==1 ? "u.name" : "")
	  .($blogger_order==2 ? "numitems DESC, u.name" : "")
	  .($blogger_order==3 ? "n.created DESC, u.name" : "")
	  .($blogger_order==4 ? "RAND()" : "")
	  ;
  $sql = db_rewrite_sql($sql);
	
  //$results = pager_query($sql, 1, 0, $sql_count, COMMENT_PUBLISHED, $uid, $uid);
  $results = pager_query($sql, $maxdisp, 0, $sql_counts);
	
  $i=1;
  while ($node = db_fetch_object($results)) {  
    //l($node->title, "node/$node->nid") .' '. theme('mark', node_mark($node->nid, $node->changed)),
    switch ($blogger_case)  
	{
      default:
      case 0:
        break;
      case 1: //smallcase
        $node->name = strtolower($node->name);
        break;
      case 2: //uppercase
        $node->name = strtoupper($node->name);
        break;
      case 3: //Wordcase
        $node->name = ucwords($node->name);
        break;
    }
      
    //Latest blog
	$sql = " SELECT n.title, nid "
	      ." FROM {node} n "
		  ." WHERE n.uid = '$node->uid' AND n.type='blog' AND n.status=1"
		  ." ORDER BY n.created DESC"
		  ." LIMIT 1"
		  ;
    $latest_blogs = db_query($sql);
    $latest_blog  = db_fetch_object($latest_blogs);
	//  
	if (($blogger_avatar) AND ($node->picture<>"")) 
	{ 
	  $blogger_img  = base_path().$node->picture;
	  $showpict = "<img src='$blogger_img' align='center'"
	           .($blogger_avatar_width<>0 ?  " width=$blogger_avatar_width " : " ")
	  		   .($blogger_avatar_height<>0 ? " height=$blogger_avatar_height " : " ")  
		       ."></>";
	}
	else
	{ $showpict = ""; }
	//  
    if (!$blogger_avatar)
	{  
      $rows[] = array(
        l($node->name, "blog/$node->uid"), //This isn't working for anonymous users.
        //$node->numitems,
        //l($latest_blog->title, "node/$latest_blog->nid")
      );
    } else {
	  $rows[] = array(
        l($node->name, "blog/$node->uid"), //
        //$node->numitems,
        //l($latest_blog->title, "node/$latest_blog->nid"),
		"$showpict"
	  );
	}
  }
  if (!$blogger_avatar) { $header = array( t('Name')/*,t('Numbers of Resumes'),t('Resume') */); }
  else { $header = array( t('Name'), /*t('Numbers of Resumes'),t('Resume'),*/ t('Picture') ); }

  $output = '<div id="blogger"><br/><br/>';
  $output .= theme('table', $header, $rows);
  $output .= theme('pager', NULL, $maxdisp, 0);
  $output .= '</div>';

  return $output;
}

The $output variable contains all the information we want to list. Namely, the array "rows"

So for some reason, the "rows" array isn't being created when an anonymous user calls this function.
