Auto category creation from post ad page
Usually in wordpress when we create posts we have the choice of specifying a new category. Is it possible to do this for the post ad field. Suppose we don't have a relevant category can we have a separate field if filled will create the ad in that specific category pending approval and then while approving ads the admin can decide wether he would encourage the category or not. This would also help to not have empty categories.
Suppose I have no category for Cameras and then a user posted an ad for a camera. He should be able to specify Camera as the category and this category has to be added automatically. The admin can then decide to change the category or move the category to a more relevant category if it exists.
