This case study presents the results of an interdisciplinary Virtual Exchange (VE) that was arranged between Finnish and Polish students in 2019. During their six-week collaboration, the students of language studies at the University of Jyväskylä, Finland, worked in teams together with their Polish peers specialising in information and communications technology and management in tourism at Adam Mickiewicz University in Poznan, Poland. The international teams combined their linguistic and tourism-promotion expertise, and, using collaborative digital tools, grappled with the tasks of analysing the official municipal city websites and promoting the lesser-known aspects of their sister cities (Jyväskylä and Poznan) in jointly created videos.
