Nope. Nonprofit registration is a one time process where we deem your eligibility participate (meaning you're a 501(c)3 in good standing with the IRS).
Every November we send all eligible nonprofits a survey which is our version of "the regular season". This survey which helps us understand your organizational structure, development capabilities, and available resources must be completed in the time allotted (usually 2 weeks) in order to be considered for participation in that year's tournament. If it's not submitted in time you will not be considered for participation.
If you're already registered keep an eye on your inbox right after the new year. If not, you can learn more about registration here: https://bracketsforgood.zendesk.com/hc/en-us/articles/209896228-How-do-I-register-my-nonprofit-to-participate-in-the-local-Brackets-For-Good-Tournament-
