Simple Suffix is a very simple plugin. It lets players set their own custom suffix or prefix. Admins can control the layout. This can be used on servers that have a donator rank. A donator can set its own suffix/prefix but is limited to layout by admins. As an admin, you define how the suffix/prefix looks in the config. This plugin is based on permissions. If an admin doesn't like a suffix/prefix of a player, he can perform /suffix player:<playername> <suffix> to set their suffix or /prefix player:<playername> <prefix> to change the prefix!
