In a previous post I asked for help in deleting form entries and was shown to a different post that was of great help. (http://www.gravityhelp.com/forums/topic/purposefully-not-save-form-in-entries-database#post-15601)
add_action('gform_post_submission_1', 'remove_form_entry', 10, 2);
function remove_form_entry($entry, $form)
Could you possibly just explain the 10, 2 for me? - The post only mentioned changing the 1 to the form ID.
