Global Address List in Mail 2.0

So im testing Snow Leopard for the company i work for, but i need to find out how to add the GAL (Company email directory) to Mail 2.0. I had a script for Entourage but i dont think its made for mail 2.0

any tips?

thanks!

just realized when you start typing the name it query's it then. and it was 4.0 not 2.0 sorry
