We need a very simple online form that people can fill out, the only thing we need is that the form must have an autocomplete or auto-fill characteristic, so  if somebody types the first 4 charachters of a name, all of the options availables will appear, so the information people fill in the form are exactly us it is in our database (no spelling and accent mistakes) and cross it with our data base, that way we dont need to check every singly survey to check for spelling mistakes.
