You can share an #OFMDFic or any type of #OFMDFanart that you've created (either new or old), or one someone else has created that you think is underrated. I think "underrated" is relative, so let's say a maximum of 300 kudos for fics, 300 likes/notes for fanart, bonus points if under 100, AND a 10% of that if it's on Mastodon (max 30 boosts)
Just enjoy #OFMDFeb2024 whenever and however you want!
