Don't update to 1.6 Yet.

Bukkit is not updated for 1.6 yet, so we can not update as of yet.

Here is how to do so.

DAMNIT i updated as soon as it came out XD

Edit: Maps are awesome but hard to use

Agh! Read this too late! D:

Nooo! I want to play this server! update it without bukkit!

As the update came out today, like formerly promised here is the .jar file to be placed in the .minecraft/bin/ folder to replace your current jar file. This will allow you to play on the server. First, download this file. Next, delete your current minecraft.jar in your .minecraft/bin folder. Then put your just downloaded jar file in that folder, and rename it to minecraft.jar. Start up your minecraft, and when prompted to update click no. If you click yes you will have to repeat the process. As for when we will actually update the server to 1.6 depends on our mods/plugins. We can not control how long this takes at the moment, but will update as fast as possible when we can. When we do, you will have to update your client. A Formal post will be made on this page when we do update as well, so check back often. Thanks.
