Looking at the following 2 modules coded for my Discord bot.
1) Twitch Live Stream Module - This module will notify a channel when a streamer goes live on our Discord. Streamer must have their Twitch and Discord linked in your profile & must have 'Name' anywhere in their stream title to be posted in the channel (Also an option to add user to a group while they are live).
2) Admin notify module - This module will notify everyone in a channel when someone joins a specific voice channel. This module is designed to notify administrators in an admin channel, when someone joins a help channel.
