The first page I went to was: ente.io/community/ where the big 3 priority links are Discord, Figma, Microsoft GitHub–these are Ente’s priority platforms. Seeing no alternative to the code forge under ‘Community’, I was curious if ‘Contact’ had listed another forge or a mailing list since this page is generally where you find email addresses. The page did not have an alt forge or mailing list, but there was a call to how they prioritize communications for their free software on nonfree Discord & MS GitHub.
Matrix sucks, but it as a chat option in the ‘better’ category. Bugs can be reported via email according to the ‘Contact’ page …but there is no other option for sending patches–not one of your 10 links.
