How to Admin or the person who create the topic can only post

Pretty much, fitness/weight loss progress is a good example as well, yoga, calisthenic progress etc. There’s definitely a market for “Timelines not on facebook” imo. I can see how it’s not specifically in keeping with the day-to-day discoursing (as there wouldn’t be any), it would be ideal as a public facing PM topic on the user profile. Think Reddit has done a similar thing, has personal blog posts on profile in one of their updates.
