This fourm is barly checked. I would go to their Matter Most site if you’re interested in contributing. Otherwise you’re more likey to get a response on the redox reddit.
From their Community page: “The quickest and most open way to communicate with the Redox team is on our chat server. Currently, you can only get an invite by sending an email request to firstname.lastname@example.org, which might take a little while, since it’s not automated. Simply say you’d like to join the chat. We’re working on an better way to do this, but this is the best way right now.”
