Just found it too. Also want to flag a recently found religiously updated labour of love which I seem to be checking every day now :-) http://britishtennis.net/
I'm completely addicted to that website circe - especially the handy charts of the top 25 GB players with easy links to profiles, draws, order of play etc. I'm one of those who knew nothing much beyond Wimbledon until about 3 years ago - now I find myself sometimes following scores of Futures tournaments in far flung places! I also check the twitter account regularly.
It's made me really appreciate how hard it is for players to get to the top - and I really hope that some of the younger players can push on and be at least a regular presence on the main tour (as we have already with Heather and Laura), and take some of the pressure off Andy. There are some encouraging 2013 rankings climbs http://www.britishtennis.net/gbtop25m/current.htm
