I'm thinking about remaking the registration form on a site I'm working on. The form is simple, but there is too much information to be filled in. It also asks if the user has already participated, in which case some questions don't need to be filled in again.
I was thinking about using a wizard or something with tabs, but I don't know if this approach will improve the user experience or if it's better just to keep the form and adjust it to look less terrifying.
Does anyone have any other ideas to make it better?
