What is the purpose of this tag? This tag is apparently for when a commission is based on a premade template, yet most of the time there's no meaningful difference between a YCH commission and an ordinary commission. The template usually isn't available anywhere I can find, so the only way you can tell it's a YCH commission is by the fact that it has the word "YCH" in the commentary.
Some of these posts aren't even commissions, they're ordinary posts where the artists says YCH commissions are open, or they're finished works that the artist says are available as YCH commissions. Like post #10326731 isn't a commission itself, and it's not even really a template, it's a regular work with the artist saying you can pay to make minor changes to it.
