Let us know where your challenge will be held (online, at your school, workplace, etc), who you expect to attend and any other interesting details! There is a 500 character limit.
Anyone can join an "open" group, while "closed" groups require an invite link and are not open to the public. You will have selected one of these options during the process of creating your group.
This is to establish your UTC time zone, and not the location of your event. Please let us know your city?
