It has come to our attention that there is some confusion regarding the "OTHER" and "OC" character tags for stories.
This is perfectly understandable, as they are the same color. I myself sometimes catch myself trying to eat stop signs for this very reason, because they're the same color as red apples.
It is a shame we all experience from time to time, which reminds us that it is important to keep the specific differences between one thing and another in mind. So, let us be more clear about the definitions in the hope that it means less time in the dentist's chair, and/or the nightmarish screaming void where the admins send people who don't tag things correctly.
The "other" tag is for characters that have appeared in-show, but do not have their own tag. This include background characters who are not fandom favorites like Lyra Heartstrings, Vinyl Scratch, or Carrot Top, as in the case of the Ponyville resident who goes by the placeholder name Wind Whistler, which was apparently given to her model by a storyboard artist on deviantArt:
Minor/one-episode characters who aren't quite as beloved as our Great and Powerful Overmare, or don't have names, like Garble and the other teenage dragons who apparently were not clued in that 1995 was more than 15 years ago now:
And even a few more prominent characters who just don't have tags at the moment, like whoever these ponies are:
The "OC" tag is for characters who do not appear in the show at all because you made them up. That includes the alicorn version of yourself you made up after huffing those paint fumes that one time, who seduces Twilight Sparkle, Luna, and Rarity by getting three MOABs in one round of Call of Duty, Dark Demon King Ravenblood Nightblade:
...or any other you made up in general, if they are a major character in the story. Remember, you only get five tags, so only pick the most important characters.
There is an important exception to this rule: if you, in the process of committing a crossover fic, ponify or otherwise include a character from a different show, a movie, a video game, or whatever, he/she/it does not get a tag. Such is the word of knighty!
Hopefully this should resolve any questions you may have, and prevent awkward encounters with the police when you're found gnawing on signage.
