What's required for to build a keep?

First and foremost I appreciate this outstanding effort. I only came upon the mod on a serious level a week or so ago. Ancients is by far my favorite period to game and this just "sucked me in". I know I can get somewhat overenthusiastic and just start "spewing" ideas. I would be privileged to work with you. Would love to talk on the phone and coordinate ideas. If you would email me a number and times that are convenient for you I would make the calls donaldcole@charter.net By the way to you use Teamspeak? I have an on line gaming group and we have a server up 24/7 which makes vocal communications free and available.

I looked at the files. What is the difference between the two and which should be tested first. I assume they should be used with your "standard" CL, DA and PCL text files which put the economy back the way it was?
