Xbox 360 halo 3 map download from computer to Xbox?

[It's me]

Ok, let's say I see (hypothetically) a great halo 3 map someone made that I wish to download. I don't know the creator's gamertag, so I can't get it from their fileshare. However, the website where I saw the map gives me a link to download the map. How would I get the map from the internet to my Xbox360 using this download link from my computer?

you must signh into bungie.net as he same email what your gamertag is set to then u go to that link and click download u can chose 8 differnet thing at a time and next time u sign on xbox live and play halo the downloads will be in your download section downloading


if u dont know the email to your gamertag then go accont management clikc windows id amd look ta it hopefuly you know your pass to it.if u dont know the pass then u can go to hotmail or w/e u the email from and try get new pass if that fails u creat silver accont go bungie sing in go link click download sign on xbox live useing that then put the stuff in file share send friend request to your main gamertag sign on to yours and go to your new accont file share and download

How about emailing them and asking for their gamertag?
