Ok, CK Lal ... being engineers, its good to see their writings. Its not bad idea to switch your profession or spend sometime in writing off the profession. Keep on writing. publish it on Nepali magazines and other journals. This is probably the last posting in this thread as it comes to San's ceiling number designed in this website. I will call this thread a celebrity thread, because it reached to its maximum limit of postings. Great job OK. Congratulations. Others who wrote in this thread should also be congratulated for writing in this great thread. As a reader I liked the thread and contents ..... Keep on moving, despite its celing limits on the number of postings. Afnai, GeoGuru
