Well seeing as you asked so politely; Registering enables you to have a network wide account with the Kaos servers, which includes access to an online currency, competition registrations, tons of bonuses, and access to our beta group to test new servers. Make sure that your IGN is correct.
The currency is a huge part of the Kaos Network, and allows you to spend it on aesthetic upgrades and access to our VIP servers. To get the currency and to make all that dolla', you can compete in network wide competitions, mini games, and donations.
Please make sure your username is your Minecraft IGN, this allows us to link the accounts to the users playing on the server!
