1. Money can be obtained multiple ways. The most sure and probably easiest way is to go to
http://www.minetown.net/vote and vote for us. Here you can get MTC which can be used to buy almost every item at the spawn market and at the credit shop.
2. Mainly, as a guest you were not allowed to talk in global and build. If you want to become a full member, if you have not already, please fill an application out at
http://www.minetown.net/promo . If accepted, you will become a member.
3. You are not allowed to break blocks becuase you are a guest. Refer to making the application I referenced in question 2.
4. You can type /vault list to bring up a list of vaults. Type /vault buy # to purchase a vault. You can get back to it by typing, /vault.
5. Once you have MTC, or diamonds, whichever is required to be used with a shop, you can right click a duckshop sign in a shop to trade your MTC, or diamonds or gold, for the item that is being sold. For example;
You come by a sign that says,
XCoaster
10 wood
1 diamond
+++++++++
This means that I, XCoaster, am selling 10 wood for 1 diamond. If you have a diamond in your inventory, you can click the sign and get 10 wood.
Hope this helps clear some things up, and welcome to Minetown!
