stop randoms and non freinds seing your playing mw3 and looking at your achievments(advised)

ok thanks to patty for pointing this out to me but you can go on the dashboard to your gamertag scroll to the right to family settings and change your profile privacy settings to custom and have it so randoms cant see your playing mw3 or look at your freindslist and block them from seing your games list and achievements just a heads up guys i new there was a way to do this just didnt no how if you have not done this already do it now stops people saying how you playing mw3 i like to reply with a controler standing on my head but for some reason they dont see the funny side lol anyway it stops the messages just a heads up guys stops you havin to apear offline
