Command Block Recipe
The Command Block Recipe (CBlockRecipe) plugin adds a crafting recipe for the command block and the ability to pick it up, don't worry, the recipe isn't cheap!

I also added in a drop from the command block!, A command block :P
Now you don't have to worry about losing them :)
How to Install!
Pretty darn simple; just download "commandblockrecipe.jar" and copy that into your "plugins" folder on a bukkit server!
TODO list
- Add a permission so that a player thats not in creative/OPed can edit the commands
- Add a permission that lets a player that doesn't have creative/OP add only the "tp" command
Note: This is my first mod, it was mostly just a "Hello World" type thing for me, so please leave comments with helpful stuff! Thanks!
