What do the country of Portugal, the city of Seoul, and the Archive of Our Own (AO3) have in common? They are all home to more than 10 million people! That’s right: AO3 has surpassed 10 million registered users this month! We at the Organisation for Transformative Works (OTW) are delighted to share this incredible milestone with you.

Even as the community is growing year by year, the active exchange of creations and ideas between fans remains as a cornerstone of fan culture. Whether it’s gifting each other fanfic, recording a podfic of your favorite story, or putting together a reclist of fics—no fandom thrives without the myriad ways fans share their passion with one another. In today’s world, where ideas are just one more commodity, and content is curated for maximum revenue, it’s more important than ever to appreciate and celebrate these aspects of fan spaces.

One way to let other fans know you appreciate the love and hard work they pour into their creations is commenting on their work. In celebration of this milestone, we have prepared a Bingo all about comments! Below you can find the bingo cards in both a square and vertical format.

You can fill out as many bingo squares as you want—the more comments, the merrier! Let us know on this post or on social media which Bingos you scored.

Happy commenting, and a huge thank you to everyone who helped us reach this milestone!
