run macro under different userid?

[Ray Maas]

I want to record my user's username/date/time when they open a particular
form in my Access database. I have a macro that does this. However, they
only have read privileges in the folder that the database is in, and I don't
want to give them full access.

How should I handle this problem? I thought maybe I could have the macro
run under another account that has write privileges in the folder, but I'm
not sure how to do that.

Or is this completely out in left field?

Thanks,
