If your language is a personal conlang/auxlang project or a very new project from a small group, we are hesitant to support the language as we do not see clear value for our community of learners. When we do allow these smaller languages access to the project, we will not feature them on the main page of Duostories.org. The course contributor would be given a direct link to share with interested learners.
