The admins on this game really let me down. I sent one of the admins a message on the 11th of January and yet no reply still. I'd like to say thats just disgusting.
It is possible that your message was missed. If by admins you mean Jeremy or myself, we get close to 100 messages a day each. I spend a good hour in the AM and in the PM going through them all. If you know the moderator that banned you, you can message them to appeal your ban: http://empireminecraft.com/XenStaff/
You have to remember they probably get tons of messages per day. Also they've been busy recently with the website having been down. So don't whine about them not responding to just one message
