Oh hey! Forum post! Again!
So, there seems to be a bit of confusion regarding the "tachi-e" tag. I've been using it as per our wiki definition, which definites it as:
Full-body standing drawing of a character. Often this is a character sprite from a video game.
Which totally makes sense! Given that the direct translation of "tachi - e" is "standing art." It also falls in line with Pixiv's definition. That being said, from how I've been seeing it used, users seem to be conflating "tachi-e" with "sprite," or even just "official art." For example:

Over 115 images tagged with tachi-e have the character sitting alone (tachi-e sitting), but a whopping none of them are tagged with sprite. Users also seem to be opposed to applying the tag to non-sprite art, which results in loads of artwork that shouldn't be tagged as tachi-e receiving the tag, while loads of artwork that should be receiving the tag not receiving it. I believe the tachi-e tag still has its merits, as the composition of images tagged as such on Pixiv make them incredibly easy to shove into a visual novel (ahem, the infamous Danganronpa pose is synonymous with tachi-e) or the sort with minimal effort.
As it stands, the number of images in the sprite tag is pitiful. Should I mass tag the sprites appropriately, and remove the tachi-e tags for cases where they aren't appropriate?
