Nicely done Ziki. And as an extra bonus, something I just found out. Namely that you don't need to create or insert a template if all you want to insert is one value from your settings.

$str = 'findthis';
$vbulletin->templatecache['footer'] = str_replace($str,$str.$vbulletin->options['kerjigger'],$vbulletin->templatecache['footer']);

Because str_replace uses up a little bit of resources, if whether or not it's going to be used is dependent on settings in your plugin then it's worth surrounding the replace code with a variable to ensure it only runs when it has to. Like so:

if ($vbulletin->options['mysetting'])
{
$str = 'findthis';
$vbulletin->templatecache['footer'] = str_replace($str,$str.$vbulletin->options['kerjigger'],$vbulletin->templatecache['footer']);
}
