Dunsfold is there and although it doesn't have any official recognition to my knowledge, the runway is very much in use. It is currently operating unlicensed and by invitation only - I was lucky enough to get to fly there myself on 15th August. The runway is indeed marked with a few large 'X's, but is also fully painted up with numbers, edge markings and so on, and is in truly excellent condition. Unfortunately a large number of pilots are using Dunsfold as a convenient turning point, and as a result you need to keep a very good lookout when in the "circuit" - I had a helicopter transit the airfield at about 800 feet just as I was climbing through 100 feet after takeoff. The airfield is also used for model aircraft flying, so don't just buzz in there without clearing it first.
Cheers,
MD.
