e621:tag types ()
Tags can be typed. There are currently five types of tag: artist, character, copyright, species, and general.
To change a tag type, prefix it with tagtype: when tagging (e.g., artist:john123). Note that tags with more than 100 posts can only be changed by mods.
General
This is the default type of tag. If you do not specify a type of tag you want a tag to be when you create it, this is what it will become. General tags are for things that do not fall under other categories (e.g., female, chair, and translation_request).
Artist
Artist tags identify the tag as the artist, like max_blackrabbit or gideon. This doesn't mean the artist of the original copyrighted artwork (for example, you wouldn't use the ken_sugimori tag on a picture of Pikachu drawn by Mellis).
Character
A character tag is a tag defining the name of a character, like pinkie_pie_(mlp) or fox_mccloud.
Copyright
A [color=d0d]copyright tag is for the program or series a copyrighted character was first featured in, like Renamon in Digimon or Pikachu in Pokémon. It can also be used for the company that owns a program or series, like Disney owns the copyright to Mickey Mouse and Nintendo owns the Mario Bros series.
Species
A species tag describes the species of a character or being in the picture like cat, feline or dog, canine.
