That ol' Discord bot in NodeJS, being re-uploaded here 'cause I lost the previous repo under the (deleted) organization.
Your wish, your responsibility. Just download everything and hit npm install to grab the dependencies, and then node . to run. Remember to insert your bot token in config.js!
This bot uses Serverwise so every message will be tracked across all servers your bot is in, and the records will be stored in your bot's file directory under the Serverwise folder (automatically created). This is enabled by default, unless you'd wish to reconfigure the scripts under events.
