Hello, according to
this topic, I am looking for an extension which could add a permission authorizing post edit only if there is no other post after (same behavior as for the button delete). The point is, even though users cannot delete their posts, they can edit them to erase the content, once they have their response.
Currently editing permission is disabled, but ideally you could allow editing until the message is answered. Even better, it would be perfect if users could edit their first post, but only to change the subject icon, to mark it as solved. I haven't seen any extension allowing this kind of thing and I don't know if it's easy to do.
Thanks for any help or advice.
