I've never taken on-line lessons before, but I did learn to speak English on my own so I guess my opinion counts for something.

I wouldn't take a lesson because for me the best way to learn would be to simply just find someone with common interests and chat, even if neither of us have any knowledge of the language (that's why we have google translate haha). I think you learn the basics pretty fast that way.

But maybe I would if I was more advanced and looking for a planned preperation for a test or something, though in that case I would probably just find a school in real life.

I regularly take language lessons. I always read feedback about teachers, their score, what do they do on lessons. And I write feedback too, so that could help other students. 

Some of the teachers are wonderful, they know how to teach, and they prepare themselves before lessons. But I had a bad experience as well, for example, when a community tutor talked to me using a mobile phone (via Skype) and didn't listen to me, didn't ask me questions, so I felt like I'm speaking to a wall. Or another teacher all my paid 1-hour lesson was telling me about his life, and he didn't start to teach me at all. 

Hi Sam

When i'll have more confidence with the english language, I'll take lessons with the teachers presents on italki.
Do you want to be my teacher in future?

That is a good strategy, but you should also take a lesson with a teacher and see.

I don't still have had the pleasure to take and plane sessions with teacher on italki.
I think that it was still soon to make it. My strategy now is that follow the discussions , try understand and make a conversation on the chat.

Dear teachers, I'll see soon
