Mailing lists
To engage in discussions with the developers, whether for troubleshooting problems, discussing new features, or proposing patches / changes please use the primary mailing list
https://mail.gna.org/listinfo/entangle-devel/
When submitting patches, it is preferrable to use “git send-email” to ensure change history & authorship is preserved. It is preferrable to send patches inline to the mail body (but ensure your mail client doesn’t wordwrap lines), or to attach patches as text/plain
IRC channels
The Entangle developers can often be found on the OFTC IRC servers, in the #entangle channel.
