An ad hoc conference on usability and effective and fit good solutions that are built around the "user experience" around.
Barcamps are created out of the need that people exchange in an open environment and can learn from each other. It is an intense event with discussions, presentations and interaction among participants.
Anyone with something to contribute or want to learn something, is welcome and warmly invited to participate.
In the event that you take part, stand one on it, to share with other Barcampern.
If you go, be prepared to share your experiences with the rest of the world.
