Active Members in forumhome statistics

[n00belit3]

I know its a new feature for vb 3.5 but im on 3.0.7 and not ready to upgrade yet. Searched vb.com and vb.org and didnt find anything. Should be a simple line of code can anyone help me out?

This is the code in index.php for 3.5 that im guessing displays the active members

$activemembers = vb_number_format($vbulletin->userstats['activemembers']);
$show['activemembers'] = ($vbulletin->options['activememberdays'] > 0 AND ($vbulletin->options['activememberoptions'] & 2)) ? true : false;

That alone does not work but im assuming I need to add a few extra things to get this to work?
