Drupal's usability team has organized a User Experience (UX) sprint this weekend (June 27 and 28) in Utrecht, The Netherlands. A who's-who list of user experience experts, core developers, and front-end designers will be present in person at the sprint.
If you're not in the vicinity of Utrecht, fear not! There will be a virtual code sprint this weekend over IRC as well. Join #drupal and #drupal-usability on irc.freenode.net. Come and put your coding and reviewing chops to good use on important issues that were identified during testing. Check out http://sprint.drupalusability.org/ for specific areas of focus, rated by difficulty.
We only have about 10 weeks left until Drupal 7 code freeze (September 1), so we need everyone's help! Drop on by, and have some fun! :D
