True, but all of those actions would require you to be a site administrator, or at least a mod. Regular community members can’t edit other people’s posts, or mess with post metadata.
Right. In the original post I said:
what if Discourse allowed users to create community-editable summaries of long, popular threads
So the way I’m envisioning it a human (or multiple humans) would be doing the writing, and I expect this would only actually get done for long, popular threads. That’s why I also made the comment at the end about whether this would get used enough to be worth the effort.
