-Go to "Program Files" in your C: drive.
-Then "Blockland".
-Double-click the dedicated.bat. Not, the dedicatedlan.bat.
-It will tell you something about typing something into the console on your server.
-Ignore that, and just go see if your server is currently up.
-If it is, join it, and people can join. If it isn't, you did something wrong.
Note: Turning off your PC or closing the dedicated.bat will shut down the server.
