Why is providing an edit button so hard btw? It’s been standard elsewhere for about a decade
Speculating here @LaurieMarlow The ability to edit a post that's already been published isn't in itself technically difficult to do. I expect the challenge is implementation from the perspective of the circumstances under which a user should be permitted to edit and whether it could (as per previous discussions) jeopardise the integrity of a discussion if for example a poster says something they later try to retract or obfuscate due to it being a lie, a dripfeed that goes wrong, various such scenarios that are not just the simplistic bog-standard SPAG error.
The ability to replace a "dodgy" post with, for example, a . (period) or xxx to basically get rid of a block of text not for honesty reasons, could have unintended consequences, such as frustration or mistrust by other posters. If they included the pre-edited post to show what edit had been made, it would make the thread a real mess, which would be a nightmare on a mobile device with small screen.
