# Modmail for Discord
A bot for [Discord](https://discordapp.com/) that allows users to DM the bot to contact the server's entire mod team.
These DMs get relayed to a modmail server where each user gets their own channel, or "thread".
Moderators and admins can then reply to these threads, and these responses are relayed back to the original user as a DM.

Inspired by Reddit's modmail system.

## Plugins
The bot supports loading external plugins.

### Specifying plugins to load
Add the path to the plugin's file to the `plugins` array in the config.
The plugin will be automatically loaded on startup.
The path is relative to the bot's folder.

### Creating a plugin
Create a `.js` file that exports a function.
This function will be called when the plugin is loaded with the following arguments: `(bot, knex, config)`
where `bot` is the [Eris Client object](https://abal.moe/Eris/docs/Client),
`knex` is the [Knex database object](https://knexjs.org/#Builder),
and `config` is the loaded config object.

#### Example plugin file
```js
module.exports = function(bot, knex, config) {
  console.log('Plugin loaded!');
}
```

### Work in progress
The current plugin API is fairly rudimentary and will be expanded in the future.
