Almost every citizen can change a law in almost every nation. However, some nations are stricter than other nations when it comes to voting. Normally all nations follow the standard referendum law on the server where the government must start a referendum when 20% of their population sent a private message to the leader of the nation saying they want that specific referendum. For more information you should contact your local government.

Many nations also have a parliament. Parliament members are able to bring up changes in laws in parliament where it can be discussed.
