Thanks to Writer Beware for this.
O, the Oprah Magazine is calling for poetry submissions.
But, the mere act of submission gives them (for no payment whatever) all rights to your work forever.
That this is a very bad idea for any writer should go without saying.4. All Submissions shall become the property of Harpo, may be edited for length, clarity and/or functionality, will not be subject to any obligation of confidentiality, may be shared with and used by the staff of Harpo and any of their affiliated companies or entities and shared with legal authorities if Harpo believes it warranted. Neither Harpo nor any party with whom Harpo shares the Submissions shall be liable for any use or disclosure of any information or Submission that you submit.
5. Harpo shall exclusively own all known or later existing rights to the Submissions worldwide with the unrestricted right to use the Submissions for any purpose in all media now known or hereafter discovered without compensation to the provider of such Submissions.
