10th anniversary giveaway addendum

Hey there, friendlies! I realise belatedly that there was a lack of clarity around my giveaway question during my livestream this week, so I'm changing the question:
What did KZbin do right after my New Year's Day 2018 video?
You have until Midnight this upcoming Saturday, 5 August to answer. To enter, do the following:
send an email to me at [e-mail]
Make the subject line 'Giveaway entry'
Write your answer and your KZbin nickname in the body of the email.
After Saturday, I'll do a drawing from the correct answers.
