If you're clutching that Defrag discount code in your fingers tightly, *now* is the time to use it. Codes will begin expiring this Friday at the end of the day, so time is of the essence.

(If you're looking for a code, use "defrag 3″ for $300 off.)

And if you need a little push, heed the words of Esther Dyson - ""This should be one of those small and memorable events where you actually meet people and hear new ideas... see you there!" - then take a gander at the agenda, and come get involved.
