When @Quanonstopped being an active contributor to the community, he bundled up all of his unfinished projects in an archive and posted a link to it which he called "Quanon's Big Sellout." It has been a boon to a few projects to this day. If you are leaving, I suggest you do something along the same lines. Just make an archive somewhere, include any possible credit requirements you might have, and let those projects continue on in the world in some way. No need to let your work go to waste. If you're leaving, do it with your head held high.
