Working paper to published paper I have a couple working papers on ssrn.com that I am preparing for submission to a journal.  If it is accepted, should I pull the ssrn.com copy from the website or block people's access to it by making it private?  Is there either a duty from the copyright change to remove it or if there is no legal obligation is there an ethical one?
Their FAQs section states:


  10. Does submission to SSRN restrict in any way what I can do with my paper?
  No. And if at any time you wish to immediately remove a paper from SSRN, you may do it yourself through SSRN HQ, or contact us to remove it for you.


Contacting them is always an option to make sure though.
