Posts Per Month

[grey_goose]

I'm looking for a plugin that will give the post count for the last 30 days... I found a couple for 3.x, but they don't work. Has anyone done one for 4.x -or- can anyone modify this one to work?

$jointime = (TIMENOW - $vbulletin->userinfo['joindate']) / 2419200; //its for a month if you can change to 604800 seconds for 1 week, 84600 for 1 day. 

if ($jointime < 1) // if they join time is less then 1 day 
{ 

    $postspermonth = vb_number_format($vbulletin->userinfo['posts']); put their current post 
} 
else 
{ 
    $postspermonth = vb_number_format($vbulletin->userinfo['posts'] / $jointime, 2); // more than 1 day.. 
} 

vB_Template::preRegister('memberinfo_block_statistics',array('postspermonth' => $postspermonth)); // puts variable into template hook
