RE: Including DUNK into the Engagement Project and increasing POB upvotes from 50 to 60 users .

Done, I delegated part of my DUNK. I'm sure you'll get great returns for us, and it will support engagement.
Something I forgot to mention earlier also, but it seems there is an issue with DUNK tokens for your post rewards calculator in your HLS tool app. It always says 0, even for posts/comments I am sure it is not 0. Other tokens, at least the ones I checked, seem to be fine.
