Group of whatsapp friends

Hi people,

I want to make a group of friends at whatsapp, to make friendship throught whatsapp. I have viber too and to talk I think Viber is better, but to start a friendship I think whatsapp is better. In this group we can talk about anything, funny things, talking about cultures and others. If you want to be a member send me a private messenger with your register number inbox at italki.

I think it will be interesting! If you won't enjoy the group you can leave anytime!

See you!
