It would be an easily added helpful tool in assessing - for those who care - who might be a troll or other type of fake (say AI) poster.
I has been in operation for years on other forums I use, along with no name changing without quite a convoluted process of emailing and asking permission and giving reasons.
I'm sure HQ are never going to modify the name changing facility now, but maybe they would listen if there was enough feeling in favour of establishing some sort of poster history (albeit quite minor) on the site?
Please vote! Thank you.
