How do I make a conversation with native speaker?

I am interested to the Lingq lesson but there is a question in my mind that how I can make a conversation with others. I look at the screen on Lingq and I feel confused of the unknown instruction on the screen and what I should do with it. Please give me a clue how to get along with other learners.

yuana, first of all you have to buy points, since the discussion with a tutor will cost you 500 points for 15 minutes.

If you go to Lessons > Speak you will see the tutors that have made time available for discussion in the language you are learning. You can join a discussion or you can request a time that is more suitable for you.

Thank you for your information. I will try it soon.
