I searched but could not find anything related to my needs. Is there a way or an add-on which forces users in specific subforums to fill in a thread form when creating one? What is a thread form? Like registration form, we must fill in to be able to register. I want to create custom thread forms and want people to fill them in when they want to create a thread. Like ebay or something. When you want to sell a car for example, you must fill in when was it built, what kind of car, color, and so on. Is there something like this already? If not, should I request an add-on or make a suggestion for Xenforo? I really need this.
