We know there's this System account in Vanilla, but what if we could have a little more fun with it? Bot is a simple framework for having the System user talk some smack, join in the banter, or whatever else you want it to say.
Grab this plugin, then follow the README to create your own plugin that builds on top of it to give you a bot with attitude.
Pro tip: Rename your System user and give it a photo. It won't hurt anything.
