I think that's all that needs to be said. ESPN bracket challenge can be found here: http://games.espn.go.com/tournament-challenge-bracket/en/frontpage
1. Create an ESPN username if necessary.
2. You're entry will auto default to your ESPN username. I think it would be easier for everyone to edit this to their TT handle. For example, my entry was initially labeled "Ravens184634 1" but I edited it to "Spivy". This can be done by clicking on the Edit Entry Info link, located directly to the right of your entry name when on the bracket page.
3. When creating your entry, there will be a Join button beneath your entry name. Click that and join Testudo Times.
4. Password is Testudo.
5. Only one entry per person.
6. Have fun!
