This bot so far has the following commands:
@LFG [minutes] - Adds the LFG role. If you are currently looking (and have the LFG role already), will remove the LFG role. Adding a number as the [minutes] will limit the number of minutes you will have the LFG role. Defaults to 1440 (1 day).
@whos_LFG - Tells you all the users who are currently looking for a game.
@info - Basic info about the bot.
@help - A list of commands.
To run it, you'll need to provide your own bot token, to be pulled from your shell's environment variables (LFG_TOKEN). In my case, I added export LFG_TOKEN="my-token-here" to ~/.zshenv (since I use Z Shell).
