The IPC decided to postpone the submission deadline of papers to TSGs due to the late production of the Third Announcement of ICME-12.

So the new deadline of TSG proposal submission is:

             November 30, 2011

But the deadline of TSG notification of acceptance stands as it is.

            January 15, 2012 Notification of acceptance

          April 10, 2012 On-line submission of final draft

I hope that the postponement will give you time to make your submission.
