Bukkit

Recoded sign evaluation to now keep track of the block interact location
Added placeholder {uses} - which will return the number of times a sign is clicked
You can use {uses:8} to have the clicks cycle between 0-7
Added placeholder {msg:ID} to get a message from the language file.
e.g. {msg{uses:8}} will have a message board which will loop through messages 0-7 in the set language file.

Some parts of the plugin will break with newer or older versions of craftbukkit.
