>Hello everybody! I don`t know English very well. But I want to practise one with you. This is my first message! Who can explain where I can chat?

I think it depends on what topic you'd like to chat. If on the technical topic, then you can stay in that forum .NET

If you want to chat on a free topic, then there is a Chatter forum here, you can add it to your profile and start participating in any kind of free discussion.
