comments section

Hi, I have two questions about the comment section. 1. The heading: leave a comment now is in the page center. We should like to have this placed at the page left side? Is that possible? 2. Adding some custom fields.I have tried to add some custom fields. That was possible, but on the wrong place. Extra fields are placed directly under the reaction field. And after that the native fields like name and email occur on the page. We should like the extra field under the name and email fields, because in the extra fields we want ask the url and we should like a remark field about privacy policy. Is that possible or is it necessary to search for a reaction plugin? Kind regards Hans Hagmeijer
