How do you change where it has the logo (like Halo 3) on your card?
You can’t do it here and according to the Halo Bulletin, won’t ever be able to.
However, until March 31st, you can change it here: http://www.bungie.net/Account/nameplates.aspx.
Go here, then click on the box that says “Game Settings” on the left, then click on “Nameplates”, which is under it.
