 ## Questions/Suggestions/Bug Reports
-**Please read the [Suggested/Planned Features List](https://github.com/jagrosh/MusicBot/projects/1) before suggesting a feature**. If you'd like to suggest changes to how the bot functions, recommend more customization options, or report bugs, feel free to either open an [Issue](https://github.com/jagrosh/MusicBot/issues) on this repository, or join [my Discord server](https://discord.gg/0p9LSGoRLu6Pet0k). (Note: I will not accept any feature requests that will require additional API keys, nor any non-music features). If you like this bot, be sure to add a star to the libraries that make this possible: [**JDA**](https://github.com/DV8FromTheWorld/JDA) and [**lavaplayer**](https://github.com/sedmelluq/lavaplayer)
+**Please read the [Issues List](https://github.com/jagrosh/MusicBot/issues) before suggesting a feature**. If you have a question, need troubleshooting help, or want to brainstorm a new feature, please start a [Discussion](https://github.com/jagrosh/MusicBot/discussions). If you'd like to suggest a feature or report a reproducible bug, please open an [Issue](https://github.com/jagrosh/MusicBot/issues) on this repository. If you like this bot, be sure to add a star to the libraries that make this possible: [**JDA**](https://github.com/DV8FromTheWorld/JDA) and [**lavaplayer**](https://github.com/sedmelluq/lavaplayer)!
 
 ## Editing
 This bot (and the source code here) might not be easy to edit for inexperienced programmers. The main purpose of having the source public is to show the capabilities of the libraries, to allow others to understand how the bot works, and to allow those knowledgeable about java, JDA, and Discord bot development to contribute. There are many requirements and dependencies required to edit and compile it, and there will not be support provided for people looking to make changes on their own. Instead, consider making a feature request (see the above section). If you choose to make edits, please do so in accordance with the Apache 2.0 License.
