Monday's registration deadline for the DIA user conference has passed, but you might have noticed you can still get to the registration page. Here's the deal: there are about a dozen spots left. We'd like to fill them, but we also need to have a final-final head count for the hotel by the end of the week. So registration is going to be held open to tomorrow, Friday, June 20. That's the stone-cold, after-the-deadline deadline; we won't be able to handle on-site registrations, so if you're still juggling plans or otherwise uncertain, get in touch with us and let us know what's up no later than tomorrow. Better still, if you want to come see Lawrence Lessig and the many other eminences of online action and Salsaness (here's the full agenda), register now!
