i adittion, i need to see, in the admin panel, a row with the nationality of each users, in order to can send private mesagges filtering by conuntry.
Can i made this with some extention?
I'm sorry but there is no way to filter PMs by country. but you can add custom fields and filter users by custom fields using wpForo User Custom Fields addon. This also adds custom fields in registration form.
