"update forum counters" cron

[meowmeow]

I would like the forum update counters script to be run from the scheduled tasks.

how do i do this?

I tried getting the section in admincp/misc.php :

PHP Code:

// ###################### Start update forum #######################
if ($_REQUEST['do'] == 'updateforum')
{
...
} 


but this script does some output to video which makes it not work from the scheduled tasks!
anybody know what i can do? should i put the full code in this thread?
