This may be a dumb question, but I'm confused about this part of the information index: http://www.cybernations.net/about_topics.asp#Tax_Rate It says "Taxes are capped at 20 days. Nations will not gain any additional income from taxes beyond 20 days." What does this mean? Is it saying that after 20 days, I will not be able to increase my income through increasing population happines, improvements, etc?
