Jenni,

Worksheets("Sheet1").Range("A1") = Application.Username

will give you the UserName in a cell (modify the loaction to suit).

Problem is where you fire it from.
If done in the Workbook_BeforeSave Event, it'll update whenever
a user actually saves the workbook.
In the Workbook_SheetCalculate Event, it'll update whenever
someone makes a change that would cause the workbook to calculate.
There are a number of other events you could place this code in
depending on what you want it to update on.

this easily?

Thanks!
