If, like me, you're having a hard time finding the JMP 18 installers now that 18 is out (yay!! good upgrade, if you haven't used it yet!), here's the link you're looking for:

Happy upgrading! I'm mostly a JSL wonk, and this version like all upgrades does have some hiccoughs for your old scripts, but it's pretty solid--and Global Pragmatica® LLC is here to help.
