I think a major motivation of a lot of "silent lurkers" (like myself) and those who actively participate on this list is to benefit from the comments of such great industry stalwarts such as Howard Berkowitz, Priscilla Oppenheimer, Pamela Forsyth, etc, etc,. They always enrich their comments with their experience, and Howard Berkowitz also adds spice to it with his wit and humour. I have read almost all his books and would recommend them to everyone seeking in-depth knowledge of networks. I think he has got a unique flair for writing. It would be a sad day for me if someone drives them off this list with their uncouth comments.
I would also name some more persons such as Chuck Larrieu, Elijah Savage, Brad Ellis, Kent Hundley, Keyur Shah, etc (and the list goes on ....) whose insights from real hands-on experiences, coupled with their marvellous ability to explain things, has greatly benefitted this list. I wish everyone a Happy New Year and greater opportunities in the years ahead. Aziz S.

While you're at it, can you provide us with a list of the RFC's you have written? And the books? I'd like to check them out. Anything to improve my own understanding of how things work.
