FAQs

Is there an age limit to the event?
Yes, you must be 18+ to join the event and the Discord server when it opens.
What day do sign-ups open?
June 28th! You can find the full schedule here.
Are there any major changes from last year?
Yes— this year, we will be returning to the original format of the event, which is that of a Classic Big Bang only. The Classic Big Bang itself will remain largely unchanged, however.
Why isn't there going to be a Reverse Big Bang this year?
In both years that the Double Big Bang was run, the initial number of sign-ups between artists and writers for the Reverse Bang was very uneven, and this led to many challenges behind the scenes. It wasn't an easy decision to make, but ultimately the mod team has chosen to retire it because of this.
