Removing tinymce from textareas

TinyMCE has a habit of popping up right where you don't want it - the log field on a node edit page is a good example.

Lucklily it is a relatively easy job to theme out tinymce for a particular textarea.

The following theme override should go into your template.php file

function phptemplate_tinymce_theme($init, $textarea_name, $theme_name, $is_running) {
  switch($textarea_name){
    case 'nodewords-description':
      case 'edit-nodewords-description':
	unset($init);
	return $init;
      break;
      default:
	return theme_tinymce_theme($init, $textarea_name, $theme_name, $is_running);
  }
}

Just keep adding extra cases for any additional textareas ...
