Do you want to make your exchange experience be more than studying, great parties and trips? You can also volunteer and leave your mark. ESN has its project of SocialErasmus which promotes doing good deeds while abroad.
More information about the project at: http://socialerasmus.esn.org/
This is now your first opportunity to get involved. There is an opening for a team through the Red Cross here in Oulu. If you are interested in volunteering send an e-mail to project-manager@esnoulu.org.
