How can I change the default system message shown on form submission I've created a business card request form as an EntityForm and am scratching my head trying to figure out where in the module i can find the line - ( " The submission has been saved " ) .

This message displays after every form submission/edit/save, and I would like to get rid of it but cant figure out where its coming from !   :)
That message comes from entityform_edit_form_submit

You could try setting the translatable text string to an empty string in settings.php

$conf['locale_custom_strings_en'][''] = array(
  'The submission has been saved' =&gt; ''
);


Or else look into another way to alter drupal_set_message text.
