There were about 60,000 non-native inhabitants of the Louisiana Purchase when it was purchased, half of them slaves. Most of them stayed where they were, and became a significant minority speaking a dialect of French in a contrary that was mostly English-speaking.
There's no need to change the game mechanics. We can already turn hammers into gold by reassigning Carpenters to do other work that turns a profit. If your lack of need for Hammers is a long-term thing, remove their profession and educate them in a more profitable one.
I've downloaded freecol-1.1.0-installer.jar, but I can't find anything that tells me what I should do with it to install the program. This shouldn't be a problem - I've downloaded and successfully installed several previous versions, but I cannot remember what I'm supposed to do, and none of the places I've thought of to check contain instructions.

A "feature request" is the right way to bring something to the attention of the developers. Mentioning it to one of them only helps if they don't happen to forget about your conversation. if the only record of such a suggestion resides in the memory of one developer, that information might effectively disappear if that developer stops working on this project. The feature request documents the issue, so they will sooner or later address it, even if only by responding with an explanation of why they...
