I think it should be split up. It'll help keep same issues for same OS's on same board. For example, if somebody wants to see if somebody had an issue with a certain OS, they can search the board that is specific for the OS they need help with. Also, it will be better for people who help as well. Possibly somebody knows more about 2000 than Vista and it would be easier for that person to help with issues with 2000 if they are all in the same place, instead of having to skim over and find out which OS needs help, especially since nobody ever puts the name of the OS in the subject.(You could always do that...make it essential that the OS is included in the subject, where they cannot post until they tick which is their OS).
