The Schoolhouse team is not granting volunteer hours for answering questions or responding to posts asynchronously in subworlds. These activities are harder to accurately track time-wise. That said, answering questions in subworlds is still one of the most impactful things you can do for learners. It can also lead to you offering Zoom Help or creating a following of learners who will sign up for your sessions/series, both of which can count for Volunteer Hours.
