Perhaps it would be nicer to have each form-field giving a green flag if 
correctly filled, not irritating the user with error messages at each 
incorrect or empty field.

I however would usually prefer to do a single pre-submit validation,
clientside for speed and/or serverside for quality,
showing commented red flag warnings at each offending field.
