Registration is already open. You can register by following the instructions on the front page of the Summit site - just look for the big orange button that says "Register". There is an early-bird discounted registration fee valid until the end of May 2008, so be sure to sign-up soon!

Please note that if you have already registered with the Summit submissions site, you can use the same login details. Also remember that this registration process is different to the one on icommons.org - if you've registered there, you need to register on the Summit site as well.
