I have tried group conversations on another website and I have found that they aren't the best use of time unless they are run by a teacher. I find a lot of time is wasted trying to decide what to talk about than actual talking. 

I think a group conversation would be beneficial if the organizer has a bit of a plan about what to discuss (i.e. a specific theme in mind) before the conversation starts.

Can you talk with more than one person on Skype? I was under the impression that you could only talk to one person at a time on Skype. Anyways, I have conversations all the time with Skype and I find it to be a very valuable tool. It's always easier to communicate using body language and speaking. Being able to point things out or send a picture of an unfamiliar word is a valuable tool.

Se puede hablar con mas de una persona con skype? Yo pensaba que no pudieras  hablar con mas de una persona al mismo tiempo con skype. Todos modos, yo tengo muchas conversaciones con frecuencia con personas por Skype. Es mas fácil quando puedes comunicar con gestos mientras que hablas.
