Hi DN
Welcome aboard. Your English is good but since you have joined specifically to improve I have pointed out a few details, I hope that is what you wanted.

Hello everybody,
I'm writing this message to see how does this forum works .
In fact I'm a new teacher of English and I've joined you to practice my English...


PS one of the funny things about English is its habit of twisting if not breaking its own rules. "How does this forum work?" is the correct form for a question but sounds odd in statement form.
