The existing plugins, after being modified, are now more flexible with the aid of a permission plugin. With CodsPerms running on your server, you can have multiple groups for players. You can create plugins that give certain players privileged commands, and yet these same players will be prevented from using commands that can be misused. This new knowledge of Bukkit permissions will give you an increased control over both your plugins and server. Now that you know how to program both commands and permissions, you are ready to dive into some of the more challenging and exciting sections of the Bukkit API. In the next chapter, you will learn how to automate your server and customize it by using the Bukkit event system.
