Meng, my point about the old cakewalk.com site is that it would only take a few hours to update the home page as a temporary measure to explain that Cakewalk has now moved to Bandlab, put a big, graphic link to Bandlab there because that would be good, free marketing for BL, put some links for existing users to access their accounts, forums etc. and redirect all the old product marketing pages to the home page or direct to bandlab.com. That way, at least you would be making good use of all the traffic that is currently hitting cakewalk.com from google and everywhere else which would further promote Bandlab. At the moment all that traffic is going to waste on an obsolete product that is no longer available and which benefits no one. The kind of traffic that is hitting those pages would convert well to the Bandlab product let alone the Cakewalk product.
I do a lot of web dev myself, and I see traffic as a valuable commodity and hate to see it go to waste.
