[Forum] Is there anyway to limit Sigs to only appearing once in a thread?

[PcosKat]

I know that people can uncheck their sig if they post a 2 or more times in a thread, but is there an admin function that I can enable that at least limits a person's sig to appear either:

1) Once in a thread

or

2) Once per page in a thread

2)

Make a plugin at hook 'postbit_display_start'

if (THIS_SCRIPT != 'private')
{
    if ($this->post['signature'] && $this->cache['sig'][$this->post['userid']])
    {
        $this->post['signature']     = '';
        $this->post['showsignature'] = false;
    }
}
