Responding quickly to ideas with "yes", "no," or "soon" is helpful to the person who submitted the idea and anyone who has visibility. But it is also helpful to your team because they clearly communicate and reinforce your positioning and strategic direction, which encourages quality discussion and additional ideas.
You can comment on an idea (publicly or privately) to capture additional context, use cases, or scenarios from your community that help clarify and expand the original idea. But when you want to make an official comment to all of an idea's subscribers, use an admin response.
Create an Admin response to publish your response as a comment in your forum. This is a special type of comment that is permanently pinned to the top of the discussion. Use admin responses to:
Thank users for their interest
Clarify the type of feedback you are seeking
Announce that you have officially shipped the idea (and link to a blog post of knowledge base article)
