On June 1, 2015, we inaugurated the lab. Guests from different places from all over the world came to celebrate this event with us. The Rector of the University of Cologne and the Dean of the Faculty of Arts and Humanities announced their presence, and prominent sociolinguists from Europe and Northern America came to take part in a panel discussion at the inauguration event. After the first part of the evening which took place in the Aula of the University, the rooms of the lab could be visited. There, we also presented our three typical sociolinguistic working stations and invited our guests for a reception. Thank you to everyone who spent this lovely evening with us!
