How can I make a custom Halo 2 emblem to reflect on my Halo 2 Multiplayer over Live?

Or other tweaks and whatnot....

well, when you first start H2, you hafta make an account just for the campaign. You can make an emblum for that. If you want that same emblum on you xbl account, when you first enter H2, it asks you to choose a profile before signing in. The emblum that is saved onto that profile is automatically used as your xbl emblum if you sign in on that profile.
