anyone have tips on doing this same thing on PC's? Or a way to read the mac on a PC? I have heard of MacDisk but was looking for a free solution.

Oh and for those that are curious. This works in Vista. I had to double check to make sure but it is nice to get this support. Now if only I could write to the disk also.

In Microsoft Office 2007 referencing formulas by names is on by default. (tools -> options -> formulas) You can also go to the formula tab on the ribbon and click on the name manager to manage whatever sections you want, or define a name using the current selection.
