Hey ... we all forgot to tell you there is a mistake in your question "to talk to each other..."

As the iTalki chat facility is pretty bad I normally use msn, skype and yahoo: - msn is widely used but keeps disconnecting - skype is quite good - yahoo is the most reliable of the 3 in my experience I swap from one to the other whenever it's needed as there's nothing more annoying than being interrupted in the middle of a conversation.

I use skype.

msn it's very convenient.

Hello For me it is also "skype"...
