STEM presentation signup at 2018 Vex Worlds

How do teams sign up for STEM presentation at 2018 Vex Worlds? I remember our team has to sign up months ahead of time. Haven’t seen any instructions on how to sign up this year yet.

There is no sign up this year. Teams that were awarded STEM research, Design, or Excellence at their state/regional/national championship will receive an email this week telling them they are on the list of eligible teams to give a presentation at Worlds. Teams will be emailed a schedule the week of Worlds once the match lists have been generated.

Note: a regional event refers to those cases where two or more states band together for their state championship.
