From the Hypatia website:
MORATORIUM ON HYPATIA SUBMISSIONS: January 15 to July 15, 2013
Manuscript submissions have grown dramatically in the last few years, and we’re building up a substantial backlog of accepted article. So, with regret, the editors have decided that we must temporary suspend all new submissions. This does not affect the resubmission of manuscripts accepted with revisions, or Diversity Prize submissions. For the details, please see the full notice here.
