For the folks outside United States, the deadline to send comments to the Final Committee Draft regarding the last C++0x draft will end in 5 days (next Monday, the 26th). Make sure to send your comments before that.
For the folks in the USA, I'm not sure why your deadline was set to last May. I totally miss the logic in that. But in any case, it's possible that you can send your comments still to the representatives of other countries, through people you know in those countries.
