I've just been looking through the tasting notes for the vintage ports - you know, the one where my notes on the Martinez 1985 would have been if my silly computer hadn't flipped on me? There are five pages, and the ports are all over the place (presumably in the order they were posted?). I wanted to read about the other Martinez (Harveys) 1985 posting, and all comments on Noval Nacional, but it was a bit of a trawl to find them.
So here we go, my suggestion after literally a day or so's membership is that a cross reference table might be a handy thing. Years along the top, houses down the side, links to TNs in the cells, and more than one per cell when required. This could live in a different place to the TN pages, or perhaps be the front page, but it would enable the interested browser to quickly find comments on a given port and year.
I acknowledge that this is probably a stack of a lot of programming for someone to do, but am blissfully unaware of the details.
