  // exist yet, this form asks for the comment with our own discussthis
  // form (i.e. avoid creating a new forum node until the person posts
  // his/her comment out)
  //
  // IMPORTANT: we do NOT check whether the topic already exists because
  // it might when the person clicks on Preview. Please, see the submit
  // function for more information in that regard. Just don't add a test
  // for the topic ID in this function...
