I run a Minecraft Server for friends and they quickly reached levels of enchanting where the anvil wouldn't allow more enchantments. Therefore it was requested to remove that limitation. Since I couldn't find any comparable plugin that does this, I decided to try to write my own.
Anvil still shows "too expensive", I believe thats a client thing, haven't found a way to get rid of it yet, it will work anyways and thats why you get a message about cost.
As of version
1.0.5-R I'm using bStats to collect metrics about servers the plugin is running on. To opt out go into
plugins/bstats and edit the config file
