You don't know that this is the third time and the third newsgroup to
which you have posted this same question?

Why you should NOT multipost:
  •  Net traffic is reduced: only one copy of your article needs to
flow to the thousands of Usenet servers. And the thousands of people who
read both groups have to download only one copy, not two.
  •  Your time is saved: You can look in one place to see all replies.
  •  Other people's time is saved: If they see that someone else has
made the point they were going to make, they can refrain from posting.
When you multipost, people in on group can't see answers in the other
group, which results in lots of duplication.
  •  Multiposting annoys lots of people. Some will tell you about it;
some will keep silent but put you in their kill files, which means you
lose the benefit of their answers to your questions, forever.
