So, as you may know, a day or two ago, minecraft 1.1 was released. Now what many people don't seem to know is all the technical issues this creates for servers and plugin developers. Bukkit needs an update before we can use 1.1, which includes many features such as bow enchantment. Staff here can't do anything, although you can Downgrade to minecraft 1.0, and get back on the server. This happens to every server that uses bukkit etc. There will be an announcement once the server upgrades to minecraft 1.1.
