yes , It is a good site but we all here for learning , so let me make a comment : 

 Hello Guys ,
I'm Mehdi ; a 20 years old guy from Morocco ; and I will tell you my story with italki .
I'm a member two months ago in italki , when I joined this website I didn't think it would help me improve my languages , but after when I (use?) it I was like an addict,
I right posts and people correct me for free hihi,I meet a lot of friends and we talked about a lot of things. we exchange our numbers and make a group in whatsup and chat all our free time and we also talk in skype about a lot of things ( ;Culture Religion ,...)
It was a great experience and I have learned a lot of things !!
Thank you italki


I'm not a native speaker If a native speaker here he can make his comment.  just for learning 

I am glad for you,Mehdi :) Good luck!
