Question

How can I disable the question body form, so that only the question title is in use?

Answer 1

I just went to yourrootpath/qa-include/qa-page-ask.php and removed the portion below (towards the bottom of the page)

                    'content' => array_merge(
                        $editor->get_field($qa_content, @$incontent, @$informat, 'content', 12, true),
                        array(
                            'label' => qa_lang_html('question/q_content_label'),
                            'error' => qa_html(@$errors['content']),
                        )
                    ),

Seems to work. That will just have the question, tags and email on answer option.
