hello i have some basic features in my osclass script, need to add some other features which are not shown in admin panel; 1. if i delete user, there should be option to delete this user's ads etc or assign it's data to another user as this option we see in wordpress. 2. there should be option in admin panel to auto relist website ads by setting time in minutes/hours/days.
