Hey Roman, here are my suggested corrections: 

How you can use ITALKI Notebook to improve your target language

I was looking for a partner for speaking via Skype when I found ITALKI. Unfortunately, I haven't found a partner yet. But I have started using notes. I realized how I can take advantage of writing my own notes and of correcting other people's notes.

My own notes.
I write a note and then someone who is an English speaker corrects it. He or she points out my mistakes and tell me how to say it properly. Usually I can't correct these mistakes just through Google or with a textbook. Then I analyze what I wrote wrong and I write 5-10 sentences with the correct grammar. I repeat this a few times for a few days. This is very good way to avoid saying it wrong next time. 

Notes of others.
I look for notes in Russian or Ukrainian. Ukrainian is my mother tongue and Russian is like Ukrainian for me. But I have to say that I prefer notes written by native English speakers. Why? Because English is my target language and if I correct mistakes from people from the UK, US or Canada, I can figure out how they think. Usually people make mistakes because of their mother tongue. They apply their speaking patterns in the target language.

For example in Russia people say "Добрый день" - Good afternoon. But when I started learning English I said "Good day" ones (once?). Just because I translated "день" like "day". This is correct. But not in this context.

I know Russian and Ukrainian. And I'm currently learning English. If you are interested in Russian or Ukrainian feel free to add me and hit me up. Thank you for your time!
