Dear Nadia,
I can see that you are very passionate about corpus linguistics, which is great to see. But, can I ask that you stop sending multiple posts to this discussion group as things come to your mind. Please think about your issue carefully, investigate the various possibilities on your own, and when you cannot find a solution, only then post a single question to the list. After posting a question, wait for a response. Don't keep posting the same question many, many times. And, when you get a reply, don't immediately reply back if you cannot understand it. Again, go away, think about it, try things out, and only then, past a reply to follow up.
I should note that many of your questions are not clearly stated, and contain numerous typos and grammatical errors. I understand that English is not your first language, but please try to check your English (e.g. using an online translation service), before posting your questions to make them clearer.
Finally, in view of the huge number of messages that you are posting, I would like to ask that you limit your posts to *a maximum of one post per day* for a while. This may be a good motivation for you to think carefully about your posts before sending them.
I hope you can understand.
Laurence.
