I think the micro and the possibility of listening (you can use your computer's speakers or a headset) is interesting, as the main purpose of these meetings will be to practice Spanish.
I've just opened my new account there. The name of this website is WIZIQ. It is a free-to-use platform.
As said above, the aim of these online meetings is learning and practicing Spanish, so please, in case you are not interested in this type of activity, don't join us. (I'm telling this because some people think a free activity gives them the right to be disrespectful.)
But if you are interested, all you have to do is to create an account, e-mail me your username so that I can invite you to our next meeting.
I've also posted more detailed information and schedules. (Click here).
