Johnny personally I do appreciate a lot all of your efforts, and especially the fact that you added the names of players who won slams or simili-slams each year
I just think that should not be lost the infos and website links (pictures, etc ...) about unknown players that you had in the previous list.
Maybe it could be put in the "blast from the past" section, I don't know but I think it should be kept somewhere
Anyway I don't think the rankings are the most important : the most important is the compilation of infos about players from the past imho.
I understand that keeping an up-to-date ranking list of where Federer, Djokovic, Nadal or Murray should be ranked is neither an easy nor a pleasant task as there will always be plenty of contestations, and I would understand that you would give up with that "slaving" goal.
