Two school years of teacher partners' collaboration online thinking about project design and application, development, reflection and following up activities and students real collaboration as it was designed, to make the most of Twinspace tools such as forums and chat synchronically or google docs in the same way. We both, teacher partners, Joëlle Hoel and Josefa Martin, have become close friends as well as partners, have developed profesionally together and have learnt together from our mistakes and from our success. Communication never failed, never ceased,, never was interrrupted and this is the great asset of our project: good communication collaboration and understanding, shared goals and aims and responsabilities in every step of this enjoyable project.
