pcor,

One way.....
Original code from John Walkenbach

Open ThisWorkbook.Path & "\Logs\GB.log" For Append As #1
Print #1, Application.UserName, Now, "Opened"
Close #1

The above explained (modify at will):
1st Line - Opens a text file named GB.log in a subdirectory named
"Logs" underneath the current directory that the workbook was saved in.
2nd Line - Append the UserName, Date & Time and the comment "Opened"
to the GB.log file
3rd Line - close and save the GB.log file.

Notes....
The directory or subdirectory that you're creating the file in must exist
but the file itself doesn't have to exist (it will be vreated the first time
and appended to each subsequent time).
Place the above code in the Workbook_Open Event or in a regular module
and name the sub Auto_Open().
