I originally created this community to post a few of my own projects and get a few others, but found retrolemmy before I could post anything. I'll still keep my lemmy.world account and all, but in the interest of keeping themes within instances, I think retrolemmy is a better fit. Admin, feel free to nuke this community if you wish! I don't see a way to on my end.
