Well, we're trying to get a nice Ubercart presence at the Drupalcon in Barcelona this year. It would be very helpful for folks to read this post:
And head over to the Drupalcon site to vote on our sessions as worthwhile events to make it into the session schedule. We look forward to spreading the word and growing the community through the event while gaining valuable insight from other Drupal developers as well.
Feel free to post up any comments or ideas for sessions in that thread as well!
