There doesn’t appear to be a way to get notified for post edits…
(both traditional post edits and Wiki post edits).
For post traditional post edits and Wiki post edits.
I always find myself here on meta wanting to know when updates are made to specific posts and wiki posts.
Watching a topic doesn’t help here.
Post based notifications for users
On Facebook whilst “posts” are more like “topics” here on meta it’s possible to “turn on notifications for post” to be notified of any activity related to the post (likes, comments).
After you change the notification setting the grey info box appears above in the feed.
I was kind of wondering if the “turn on notifications for post” could be added to Discourse posts or something similar?
