I'd like to share how I know italki.
Our company hired a new colleague. My boss told me to tell him about our company this morning. I was surprised that his oral English is great. I asked how he did it and how long it took him. He is a nice guy. He recommended some methods to me, and one of the ways is italki. He told me it really works. I hope so. So I am trying and wish to know some real-life friends.

I understood the general entry, but the sentences were a bit tough because there's a lot of ways to change them depending on what you want to say. Also, for formal writing, you can't start a sentence with "so".
