First of all, welcome!
I had the same problem when I first started, and was especially confused since it was my first server!
If you want to get started, here are some useful things to know:
-Most of the community is very helpful! Ask us in the chat if you have a question!
-Wooden axes are server tools, so before using one, type "/toggleeditwand"
-"/home" takes you to your "home" location. To set a home, use "/sethome"
-Type "/money" to see how many MT credits you have.
-Finding clear, unprotected land can be hard and time-consuming. However, the /home command will help you set little 'checkpoints'
and if you get hungry or hurt, feel free to type "/warp heal", which takes you to a sign that will totally heal you!
-Making MT credits is as easy as voting. Voting can be done with that button up there More>vote!
-Using credits, go to /warp marketplace and buy things, or even buy your own shop!
-Consult the minetown wiki for info on commands/plugins
-Making money and finding land are the two big things to do, so by the time you do those,
if you are active in chat, you'll know everything you need to know, and have a good time doing it!
I hope that I could help, and hope that you enjoy your time on the server.
