ChatPrefix is a plugin created using the Source.Python server plugin for Source-engine games. As such, it requires Source.Python to be installed on your Source-engine server. It currently only supports CS:S, CS:GO, and TF2.
This plugin adds prefixes to chat messages.
To install, simply download the current release (not currently available) and extract the contents into the main directory on your server.
Once you have installed ChatPrefix on your server, simply add the following to your autoexec.cfg file:
sp plugin load chat_prefix
After having loaded the plugin once, a configuration file will have been created on your server at ../cfg/source-python/chat_prefix.json
