zChat

This is just an updated version of zChat which was never released. I managed to update it and build it and decided to release it here. Here's the original description from its bukkit page:

zChat is a very simple chat manager for Bukkit. It was optimized to work with zPermission and requires Vault (other permissions plugins which uses Vault should also work, I only tested the plugin with bPermissions).
List of features:

• color chat
• local chat (optional)
• prefix/suffix support
• Factions support

zChat was originally forked of the bChatManager which was originally forked off the PEX ChatManager.
Installation
Make sure you have following plugins installed and configured:

• Vault
• Vault-supported permissions system (there is a list on the Vault page)

Put the zChat.jar into the plugins folder and the plugin will generate a config folder.
Config

• message-format - Format of a chat message when ranged mode is disabled or a global message format if ranged mode is enabled
• local-message-format - Explains itself
• ranged-mode - Disable or enable local chat
• factions-support - Disable or enable factions support. Be sure to disable that, if you don't have Factions plugin, otherwise you will get errors
• chat-range - Local chat radius

Available placeholders: %world, %prefix, %suffix, %player, %message, %displayname, %faction
Place "!" before your message to write in to the global chat.
