I found this extremely useful. Although kdpp6512 now has a guide on adding civilizations, I think this is much easier to understand and uses less programs. This is also useful as a guide for anyone who wants to access other information. I highly advise you download this.
Additional Comments: I wonder if it would be difficult to delete a civilization. It might prove useful for making conversion packs...

I found this utility very useful. This turorial teaches you how to change the names of civilizations. In the tutorials chase, Mayans to Canadians. This is good if you are making something like an LOTR Scenario and you wish to change the civ names.
Although kdpp6512 has made a tutorial on unlocking your nineteenth civilization. I find this turtorial much easier to understand and use.
