If you create a booster now, you can choose whether it applies to posts or to the comments or both.
Thanks to @Babita de Boer !

For this topic #discussie I put a booster on the comments. So only on the comments. How cool is that:)

You as a poster start a discussion. People with the most votes on the comments. With the best contributions so... receive the booster premiums.

Enjoy and try this out by creating a booster.

Booster adjustable for comments and/or posts
