InfoMan is a simple and easy-to-use motd/informative commands plugin with support for permissions for each individual command.
Example:
motd
info
Only console input is accepted, you can disable and enable motd by writing: "infoman motd e/d", where e enables and d disables, motd is enabled by default.
You can also disable the "first join" message by the same principle, "infoman firstjoin e/d"
The plugin is reload-able, typing "infoman reload" in the console will reload commands.txt and the config.
