Futoshi Nakahara, CCIE #19600
Dear IEWB staff, Thanks to your kind support finally I got the my number #19600 last month. Although I purchased a IEWBv3 printed version, IEBW gave me a IEWBv4 account for free. This electronic up-date is awesome and very helpful. I purchased only IEWB, not other workbooks, but this is enough material for success I feel. Again, thank you for your support!
