A couple places:
- chat.piefed.social - real-time chatting with users/devs using Zulip (you can log in with your piefed.social email+password, or create an account)
- There is a public matrix space if you don't like or want to use zulip.
- This community or !piefed_help@piefed.social are good places to provide feedback if you want
- The codeberg repo is a good place to create issues that are more persistent and where you can keep up to date with active development efforts
