Nice platform! I use it for small language classes for teenagers. It took some time for my students to learn the tool, but now it is so much fun. I can not only explain the grammar, using shared screen and various pinned materials, but also run some engaging activities like "find the object game" or "matching the words and the pictures". And group work is really easy to organize! Students just need to move away from each other to hold different conversations at the same time in the same environment.
