Security announcements will no longer appear here

[Ned Batchelder]

Hey all,

We used to send all announcements of security fixes to the edx-code and openedx-ops lists.  In an effort to simplify, we are now only sending those announcements to the openedx-announce list: https://groups.google.com/forum/#!forum/openedx-announce

If you have a concern about this change, please get in touch.

Thanks,

--Ned.
