Add a field to your table(s). Store the user's name/initials in the field.
Add TWO fields. One is for "new" and one is for "changed".
Add FOUR fields. A pair for new (who and when), and a pair for last
changed.
In your forms (you ARE using forms, right, not entering directly in the
tables?!), add code behind the form in the BeforeUpdate event to fill these
additional fields.
You can probably find examples at mvps.org/access, or by using Google.com to
search.
Good luck
