I joined a group call on Skype before, it was awesome. In my point of view this kind of practicing is not only improving English, but also shares knowledge about different things like culture, health ...etc

Whoever want to join the group, it will be like picking random topics to talk about, as if we are playing spin the bottle, every one of us will take his/her turn to express him/her-self, opinon, topic...etc

Welcome to any speaker level, just type your Skype name, and lets co-ordinate the suitable common time.
