Learning/improving English is fun!:)

Hey, i'm new on this website and would really appreciate any help to learn a bit more about it. In order for you to help me at first i should help you to learn a bit more about myself. I'm 15 years old, i have been learning English for quite a long time, and i want to experience talking to people and, of course, improve it more. How to start a conversation online with a person? Or if it's not possible on this website, could you please advise me another website(s) where i can do this? Thanks in advance :)
