So, as you guys may or may not have read... 1.2 will be officially released tomorrow (March 1st). (YAY!)
What this means is... we will not be updating the server until there is a stable Bukkit release for 1.2. We cannot update the server because our plugins will not work, which is a huge invitation to griefers.
So, hang in there, install 1.2 for single player, and I'll be updating WonderHowTo's server to 1.2 as soon as I can!
