Watch for all these new gamesave webistes popping up. All they are trying to do is get you to register so that they can grab your email and password. With this info they can take your email and your login to other sites and forums and even your gamertag if you use the same info for everything.
Also if someone comes on here saying I'll give you a 360GS invite just send me a PM. Most likely it is the same guy Agent who is scamming everyone for 1600MSP. All he is doing creating new names on here posting the same info.
So if you want to join ALL of these NEW site gamesave sites go on yahoo.com and make a BOGUS email and a fake password that doesn't tie into any of your real info.
