You can join Cafe de las lenguas every Thursday evening in PS! in Groningen. This is a great way to meet fellow language learners and to be able to practise your language skills. You have a good chance to meet native speakers, who can help you improving your fluency and pronunciation. You can learn and benefit from each other in various ways.
Facebook and Appear.in
However, if you cannot make it to the regular sessions, you could meet online too. Not only is there an active group on Facebook, but you could also meet online through Appear.in. This tool allows you to talk online. You can access this videoconferencing tool through your desktop computer, laptop or through the smartphone.
