Lullabot recently announced a Drupal training conference called Do It With Drupal which will go above and beyond their normal, sold-out workshops. Attendees can expect to learn a lot about Drupal and its major contributed modules from the developers themselves. If you're investigating Drupal or Ubercart for your business or are considering developing sites more regularly, I highly recommend looking into this conference. It'll be worth the price!
I was lucky enough to be invited to present Ubercart sessions and couldn't be happier! I'll get to fly down to New Orleans as the winter weather sets in heavy in Louisville and hang out with all the great presenters and the lucky folks who register before the conference fills up.
Space is limited and the first 100 registrants get the best deal, so register soon if you want to come learn about Ubercart with me and the others who show up.
