——– description
	due to phpArcadeScript excessive use of global variables attackers
	can very easily inject xss into various portions of the application

	in ./includes/tellafriend.php:

21 	22 if ($about == "game")
23 	{
24 	echo $gamename;
25 	}
26	
27	 else
28	 {
29	 echo $site_title;
30	 }
31	 ?>

	this poor coding is repetative throughought the application, possibly
	having more vulnerabilities present in the coding.
