Hiii!!! I have many species created, but I heard that to prove that they are yours you had to publish it on "x" page (I don't remember the name, and I don't mean Twitter) to the closed species so that they can't be stolen/prove what it is yours and be able to sell them since this way the buyer is sure that they are yours and closed species.
Does anyone know how I can and where I should publish it?
(or if it is free to publish it)
