Though I feel this idea could potentially be relevant to all posts. I was thinking specifically for say server threads: The ability to pin posts on a thread.
How would it work?
Pinned comments would appear at the top of a thread chronologically. And once the person starts to scroll the entire thread would collapse and appear. Only the owner of that thread would be able to pin messages.
Especially in server threads -often become full of off topic day to day server stuff, it would be very help full for important server updates and announcements. Would also be a interesting way to preview a servers journey.
