The original poster, dani_cv_74, posted this question multiple times, in different sections of the Monastery; probably unable to find his original post.
For an understanding of where each type of post belongs, please refer to The Perl Monks Guide to the Monastery. Once a message is posted, it doesn't need to be reposted again. It may take a few minutes for a high ranking monk to approve the node into the section where it's been posted (or move it to the appropriate section), but have a little patience and it will happen. ...and if it's a good node, it might even get sent to the Front Page of the Monastery. For details, you might want to read Why can't I see my post?.
All of the "reaped" duplicate posts will be reparented under this node, just to keep the clutter down.
