You can’t. There’s also no Report feature inside of the inbox or your profile, so if people send you really foul stuff there’s no way to bring it to zeni’s attention.
You can report one of your posts to request deletion and a moderator will look into your request.
Thank you for reply its not a post I want to delete its personal msgs sent to my forum inbox and wanted to know if there was a way to delete them.
Reverb kindly answered my question that its not possible would be a great idea if such a feature is implemented in future 🙂
