So I posted something for a challenge and after I posted it I realized it wasn't a successor and all the creations that were built for the challenge have to be a successor. So I was wondering is there a way to make my build I already posted a successor of the challenge or do i have to rebuild my creation.
You may tag me on your post, and provide a link to the challenge. I can edit successors.
Save it as a sub assembly, then post it as a successor.
