I have a question, why can't we place the new blocks or world edit them? Please answer. -Laura

Bukkit has not been updated to 1.7.2 yet, so we are using a so called protocol hack of Spigot. This allows 1.7.2 clients to connect to the server, but it doesn't have the new items that were released in 1.7.2. Nobody knows how long it will be until Bukkit gets updated. Until then we will stick with this "fake" version, if you'd like to call it that. :)
