Could be done. This code should expand any shortlinks given to it to
their full links. I think. Works on the ones I tested it on. Feel free
to pound on it for me.

function expand_shortlink($url) {
	$headers = get_headers($url,1);
	if (!empty($headers['Location'])) {
		$headers['Location'] = (array) $headers['Location'];
		$url = array_pop($headers['Location']);
	}
	return $url;
}

I can implement this as a plugin for the forums, unless anybody can
find fault with my code. :)
