Trivia Question Etiquette

Trivia questions are multiple-choice. If unsure, it's okay to guess! If you know the answer, no explanation is needed - it makes things less fun for those after you.

After the correct answer is revealed, sharing related facts or personal stories is encouraged, but save detailed discussions for the end of the session. Let the Net Control know if you have extra information to share afterwards.
