It’s easy to find the email addresses of Quod Libet’s authors and maintainers, but please don’t email us directly unless asked to, or if it concerns us specifically. If you contact just us, it means no one else can help you, and we can be really bad about replying to email.
If you have a question or want to report a bug please open a new issue on the GitHub issue tracker.
If you want to address the wider Quod Libet community consider sending a mail to our quod-libet-devel Google group.
Quod Libet has an IRC channel on OFTC , #quodlibet. It is a good place to ask for help with installation and configuration, or discuss development (assuming people there are paying attention).
