I need a module which can log form data and let the user edit it later. It is for a website where people will be applying for grants. They probably will not be able to fill the whole form out in one sitting, so I need something that can save it so they can come back and finish it. I have looked at Formulaire, but it doesn't not have this save functionality.

Does anyone know of anything like this out there? Or some other way to do it?
