Tim,
Thanks for posting this. I would have missed MadReferee as soon as there was a post asking about hydraulic problems and he didn't answer within several hours. Its clear this website was important to him. I once posted an invitation to Mad to write a book on tractor hydraulics- he had a captive audience here. Others chimed in too but Mad seemed too modest about his insights.
A lot of good people come and go on this site. After awhile, when you notice, you always hope its because other priorities crowded this one out. But you always wonder.
John
