yes it's possible:
edit newreply.php, newthread.php, and editpost.php and find this:
PHP Code:
$message=censortext($message);
After that add:
PHP Code:
$message=preg_replace("/(,)(\S)/", "\\1 \\2", $message);
This is for all users.. If you want the hack to apply to a certain user use this instead:
PHP Code:
if ($bbuserinfo['userid']==X)
{
$message=preg_replace("/(,)(\S)/", "\\1 \\2", $message);
}
Replace X with his userid.
Enjoy..
