I want to make a form, for example a leave application form.
when the staff sumit the form, admin will receive a mail and admin's
database will be marked some information to calculate the balance of annual
leave.

I used Application.UserName to make a form.
But I find that some people have changed their user name or remove the user
name.
for example, the deflaut name should be "mkelly", but their change it to
"Mick Kelly".

So, I cannot match the user ID in database.

Can I get the computer Login name in Macros?
Thanks in advance.
