[AccessD] How to do an Admin Table

Forgive me, if this is an easy one, but I've even asked someone that
teaches the Microsoft Access certification classes, and they didn't know
how to do this either--or maybe I wasn't clear, when I asked.
 
I have had many programs where it would be useful to have an "admin"
table. This table would contain one single record with information
referenced in other parts of the program. For instance, I have a program
that figures monthly mileage for our county legislators, but it is
currently setup so that the rates are hard-coded and I have to alter
them everytime they are changed. I would like the user to alter this
themselves.
 
I have also thought about using this for programs--maybe in their
splash screens--to list the current directors names, and other info that
may or may not change in the future.
 
Any ideas how?
 
Thanks ahead of time...because I know if it can be done, somebody on
this list knows how to do it!!!
