@randomb01: We'll upgrade when there is a stable 1.4.2 Bukkit release out and all of the plugins we have are supported. And you can revert this - download or retrieve a minecraft.jar file for Minecraft 1.3.2 - NOT 1.4.2. Once you've gotten the .jar, replace the current one in your ".minecraft/bin" folder with the one you've just gotten. And when you re-open Minecraft, DON'T click "Yes" when it asks you to update.
If you want more information on replacing your minecraft.jar file, please refer to Google.
@mhunhammer1999: If you haven't already been ranked, I've done so. Enjoy the server.
