I Forget how to add a new Civ! Help!

[Big Bad Abe]

I forget how to add a new civilization into the game, although I've already added the Austrailians into the game without difficulty a while back.

Can someone HELP?

I attached an archive wich contains a civ3edit file with "add" and remove buttons enabled. This way you can change your tech tree and add/delete civs.
