While looking in the latest Discourse commits I saw a “wiki topic” commit in the master branch. It seems a new kind of post are coming : https://github.com/discourse/discourse/pull/2303
Associated discussion on meta.discourse:
Oudeyer test: This is a post editable by others (everyone ?)
I upgraded the forum. This topic has now the wiki feature, meaning anyone (?) can edit it.
I could edit the first post in the topic, but not your latest post. Maybe something in the setting should be changed ?
I think the idea with the wiki feature is to allow the first post to be the actual wiki post and the replies a way to discuss the content.
Now, the big pen icon is clickable and permits to edit the wiki post.
