For this project involving 32 eTwinning schools we decided to share our documents in google drive.
A google account MrBean.pulses was created. 
Powerpoint presentations are embed as google slides and videos on youtube.
This account was also used to create a blogspot to facilitate the communication between the teachers before the beginning of the project . This blogspot involved 37 contributors of a google group (eTwinners and non-european teachers) http://mr-bean-and-mrs-lentil.blogspot.fr ; it was a fair solution for non eTwinning teachers.
