Welcome to YAMS, you'll be happy to know that I have now gone ahead and whitelisted you (make take a few minutes), I really hope you enjoy it here!
Once on you will be greeted by a Community Support officer and shown around (rules/sandbox/mining world etc), if however no CSO or other member of staff is on to greet you then please proceed to the rules room by yourself and read all the info from that room and then the other rooms as needed
from there please proceed to sandbox north of spawn tower on ground level (use /compass). In sandbox you can start building a house and get yourself approved to move to a town, more info explained in game about this on the sandbox rules board which is located at the entrance.
Please make sure you read everything that need be, as it explains everything and ensures everything runs smoothly both for you and me.
