ou have said it rightly on the subject matter.  Despite many reminders from you and Mr. Rangarajan that it is illegal to download or upload copy-righted books, articles and software materials, quiet a few sefians keep on doing it regularly in this forum.  Such people do not have any regard for the efforts the authors have put in in making these materials.    For them, 'SEFI' means 'Structural Engineers' Free Information'.  They want fat salaries for themselves, but do not want to spend a small part of it in buying books and software.    It is a very bad trend indeed.
