You can post stories with the MLP characters as Disney Princesses, Disney Princesses as MLP character, or any other way. For MLP characters as Disney Princesses, we like certain ponies as certain princesses. You don't have to follow this rule, but you should. You really really should.

Twilight Sparkle: Belle (Beauty and the Beast)
Applejack: Cinderella (Cinderella) OR Rapunzel (Tangled/Rapunzel)
Rainbow Dash: Pocahontas (Pocahontas)
Fluttershy: Snow White (Snow White and the Seven Dwarves)
Pinkie Pie: Ariel (The Little Mermaid) OR Merida (Brave)
Rarity: Jasmine (Aladin) OR Mulan (Mulan)
Spike: Jasmine's tiger or anything else you want him to be

You can vary the characters, but we'd prefer if the Mane Six were the Princesses listed. Thanks.

It's not the only thing you can write about, but we do prefer it if you do.

If you have other stories, please feel free to add them. We will not penalize anypony for posting them.

This just makes it easier for everypony.
