Let me update this. There is now a starting time. It is 16:00 July 8 UTC, which is 9 AM July 8 Los Angeles time. It will be on the Polymath blog.

Let me update this, It has started.

Let me update this further. There are now two solutions here and

There is also a discussion thread and a wiki page.

There is a new thread for Polymath5 here.

Polymath3 will deal with the polynomial Hirsch conjecture. Here is a post about the Hirsch conjecture. Here is another about the polynomial Hirsch conjecture. Here is a link to various materials about the counterexample to the Hirsch conjecture including a television interview.
