Hi @Brian093 thank you for asking 😊
Free courses do not offer a certificate of completion. Additional course features like the Q&A and direct messaging are not included (even if enabled by the instructor) in free course enrollments.
The lowest price you can set on a course is $19.99 which might be lower if you opted-in to the Udemy delas program. You can learn more about the Udemy Deals Program here.
