As a long-time technology forum moderator (using many different online collaborative tools, some of which pre-date the (r)evolution of the internet to today's WWW), I wish to express my profound disappointment if Symantec cannot appreciate the value in keeping the old forums available, even if only in a text-based format.
Maybe Symantec believes that they can sell "sizzle" instead of "steak" and still be successful, but that just isn't a viable long-term strategy. As a senior IT person, I value knowledge, especially that gained & shared within the customer community. The company that recognizes that will get my vote of confidence every time.
Come on Symantec, do the right thing - make the old forum(s) info available, in some format.
