I'm thinking of splitting the stories into two folders: one for stories featuring a Doctor who has always been a mare, and another for stories in which the Doctor regenerates into a mare.
1. What are your thoughts on this?
2. What's the best way to label these?

folder for already mare: perma-mare
folder for regeneration: Respawn-mare

2003756 I was considering "Alternate Doctor" and "Regeneration", but just saying "Regeneration" sounds too ambiguous, and anything else might be a bit of a mouthful.

Alternate Dimension = Professor Whooves (AU)
Regenerated Mare Doctor = Doctress Whooves. (Reg.)

Thus you name the folders by the most likely names.
Just remember K.I.S.S.-
Keep
It
Simple
Stupid

Or you know. Just Classify one as "Wibbly Wobbly" and the Other as "Timey Wimey"

2003857 That one reminds of that restaurant on The Simpsons in which the washrooms were marked "Cool Cats" and "Squares".

Check New Post, in which I was too stupid to make it a reply to you as well.

2003886 I saw it, actually. Regenerated Mare Doc works pretty well, I think.

Alright, I've set them up as "Alternate Doctor", "Regenerated Doctor", and "Other".
