Personal Messages and Audio talks

[insidee]

I'm new to Duolingo, so I'm sorry if this was already been discussed before. But I just started to look after people who also are learning the same language as me (German) and I noticed there is not a Personal Message option in their profile. Also a Audio chat option, much like in Livemocha, would be really interesting. I think these tools would only improve our language learning! What do you think?

you can post a message on their stream, but it is true there is no voice chat.
