Just SBD and Steem.
It's as a top level post. If you use steempeak you can select to hide it on your blog with a toggle switch when creating your task. If I had seen what tokenBB was doing (all posts as a comment) I could have created it as a comment on a generic top level post (via @steemtaskr). Off the top of my head it might be possible to change it to such a state, so I will keep it in mind if the platform starts to get more use. Thanks for the idea! :)
