I think I have a four player table solution that everyone will appreciate.
Why not set aside a certain time, say, six hours a week, where one of the two player tables becomes a four player table?
It would mean that people who wanted to play four-player games would have to coordinate, but it has the potential to raise site traffic here (having a four player itinerary board here) and traffic on GCCG will remain the same.

Maybe a week out of every month would be better than six hours a week? At least that way wlk wouldn't have to be changing things so often and everyone should get a chance during that week to play a four player game if they want too..
I think the four player table being brought back somehow would be great though if possible, it gives deckbuilding another element and games are fun.
