Hey Scoop,
it doesn't really matter which way you ssend your trade offers, but you should probably go into ESPN and set up your trade preferences.
If you go into ESPN and click on "My Team" and then click on "Trading Block" it will bring you to a screen where you can set up your trade profile.
It also links to every GM's email and allows you to send them trade offers.
I see that Greg, Keegan, and Mike have done it so far. Would love to see everybody do this when they have a moment.
Cheers,
Matt
