Congrats on your company hosting a Madness Bracket!
For an overview of what Giving Madness is and how it works, feel free to check out this all inclusive blog post.
While the games are running, you will be able to view the bracket in real time and submit your vote directly through your Millie profile.
You also will receive emails to the email associated with your account letting you know that the games are about to begin, on the days each round is running, and after the games have completed letting you know the winner (remember though - all the nonprofits end up winners with each getting a percentage of the overall monetary amount!).
Now, let the games begin!
