Yeah you gotta have some to maintain order, this entry may change at any time:
1. If you are submitting Original Ponies, do it in the OC ponies folder.
2. If you are submitting PONYSONAS, do it in the PONYSONA folder, not the OC Ponies folder.
3. Fanfiction OC and Fanfiction Canon are just that, for fanfiction ONLY. Any mary sue/barry stew-esque fanfics which include any OC/ponysonas alongside canon characters, place these in the Fanfiction OC folder.
4. Please don't submit any suggestive or explicit images. (No, twilight sucking on a photoshopped Subway sandwich isn't allowed either) Keep shipping to an appropriate level.
