We’ll be posting trivia challenges throughout the Community Day event!
The best answer for each challenge will be marked as a solution and earn the poster a promo code for $100 of Atlas credits and a Community Day 2021 Trivia Winner forum badge that can also be used as a title on the forums.
A great answer will include some information such as a link to more information or a tip on how you figured out the solution.
You can help us decide the best answer to a trivia challenge by liking great responses! To give everyone a chance at earning Atlas credits, we will use “have you already had a trivia solution accepted” to break ties in favour of those who haven’t had a solution yet.
