THIS HAS BEEN REMOVED AGAIN BECAUSE THE ADMIN CHAT WAS DISPLAYED! HOPE IT GETS FIXED!
From now on you can use a webchat if you’re at least Premium on UnityCraft! Simply go to the Dynmap page, click register on the lower right. Then go inGame and type: /dynmap webregister. Then type in the stuff required and you’re able to use the webchat. Don’t use your Minecraft password here. Have fun! 🙂
