Ship Sunset with an Equestria Girls *or* MLP (Friendship Is Magic) Villain For a Contest by April 8th (Time Zone: United States, Eastern) · 4:45am Apr 4th, 2022
You can put your normal-length story on fimfiction.net the normal way, OR use the contest's unusual blog option that lets you enter a story under 1000 words.
Last time I checked, only one story has been entered so far, so I guess your chances are wide open!
Update: At least one unusual prize might especially interest people who follow Mockingbirb on fimfiction.net.
