Hi Jay.
I've just noticed phpbb allows folders in the user control panel for managing PMs, but it appears to be turned off on this forum?
You can go to Rules, Folders & Settings, and the ability to add a folder is there - but no Ok button or suchlike to action it - and there's no dropdowns to move folders into them once you've created them.
As an author of four plugins, I've got loads of "threads" of plugin-related PMs which I'd love to move into plugin-related subfolders for ease - any chance?
