Given the transformative powers of SCIENCE!, shouldn't Cloning have M/F as an option, or would that be posted under Rule 63 despite being about a cloned R63 copy?

I'd probably put in under Rule 63. The folders are hardly exclusive nor all-inclusive, so... I'd say either folder would probably work. Whichever the author prefers, I suppose.

EDIT: And any suggestions folder-wise would be nice. The current ones are just the four manners in which I've seen self-shipping happen, so I figured, y'know... organization!
