@Art I also had problems with a student on Monday. He could hear me but I could not hear him. The connection was impressive. Even without him knowing what it all was about, we were connected instantly but then, the sound problem let us down! Are there yet a few tricks to be mastered?
In theory, Gruveo seems like the perfect tool to connect users on italki for a voice chat: fast, easy, works on the fly, no engagement (list of contacts), and a few other convenient features. But is it in fact as easy and effective as it is in theory? Is it just a matter of practice with the tool or are more advanced computer skills needed to make it work?
It would be great to have a voice chat tool like Gruveo available for getting in contact instantly on a site like this. However, the useful tool here is the voice chat (alongside a text messaging box), not the video chat, so it should be really easy to make the sound work (independently of the camera), otherwise, all the prospective usefulness of a tool like Gruveo would vanish for many of italki users.
