Re: the reason for asking three times
You don't need "messenger." By the way, most of us refer to that feature as "Private Messages." You may elect to accept them, or you may not. It is your choice.
But look at the bottom of this thing I am typing. You will see three "buttons." They say "New Question or Topic," then "New Poll," and finally "Post Reply."
If you hit the "Post Reply" button, what you type next will show up as a continuation of the same "thread." But if you hit the "New Question or Topic" button, it starts a brand new thread, and it is not linked to your first question.
