Hello Marina italki is not a chat tool.It is a website where you can learn any language.You can do it many different ways.For example you can find a teacher and have lessons using Skype or another software tool.You can find a language partner and do an exchange (you teach something and they teach you).You can ask questions and people will answer you.Or you can write in your journal and people will correct you.It's up to you what you do here.Good luck!
