It seems that they finally woke up!
As a regular visitor to their "Vintage Port Site", I kept reading the message about a re-design and new launch of that website for quite some time (a few months, in fact).
Well, it seems that the long wait has paid off, at least I liked what I saw. Lots of new features and information can be found there, including a virtual cellar-management tool. They have also maintained the old address (http://www.thevintageportsite.com)
I think a new face-lift from time to time does the Port industry and their respective aficionados only good.
