If you, as an organizer, have already made the event official and notice, for example, a wrong scores or a missing player that you want to correct, you should contact FIBA 3x3 user support and ask the event to be re-opened.

Remember to mention clearly the exact name of the event, and if possible, copy & paste the exact web address (URL) of the event as it shows up in the play.fiba3x3.com Event directory.
