I want to know that whether full name or first name and last name is better to ask in user profile or registration form?
For example: My full name is Waheed-ud-din, where it is one name, so no separate firstname or lastname. I can use my family name with it, as lastname. But I usually don't use that. I normally use Hafiz as my firstname that is my nick and most people know me with that.
So should we use display name during registration and during profile completion use fullname? It seems good but problem arise when display name and full name are totally different and we need to show fullname at some places and username/displayname at some other places. Some time user can be confused because of it. What do you think could be the solution?
