What I'd love to see is a revamped site that is more user friendly, to bring back more people and keep the discussion about wine alive.
If I remember correctly they got forced into this format by a European privacy regulation. They did not want to get rid of the forum but it does not benefit them much either. If you Google 'internet forums dead' the first article that appears is titled "Internet Forums Are, Generally Speaking, Long Dead; Don't Do Them". I would hate to see the forum end and would love to see a better format draw in new users but that looks unlikely.
