Hello, We haven't heard back from the Matrix folks (which you introduced rather abruptly in the conversation) about whether users on the Matrix side could be moderated from IRC.
I don't feel like there's a strong will from the current Guix IRC moderators/maintainers to take ownership of a Matrix official channel. If this perception of mine is false, make your voice heard :-). Otherwise, I'll close this issue in a week or so, as there is no point in leaving it to linger on forever. Thanks, Maxim
