How I discovered italki

I discovered italki through a friend. It's a very good idea, but sometimes I'm a bit confused (? this usage is correct) by the interface. I'm also not sure also of where to start first, or how to be sure not to miss things. (Yes, I hate that! The notifications disappear after one view! Scary!)

But I like it a lot, and I wish I had more time to use it and practice English or other languages…
I'm very impressed by the number of different languages some people here speak!
And that was my exercise for today (I wrote "exercise" differently but my computer has kindly corrected it)…

 "I'm not sure also of where to start first" -- I'm also not sure where to start first. 

Small correction, the order of words in sentences in other languages is what I find the trickiest bit to learn. 

Thanks for your help again!
