Although there were some positive responses (on list and on irc) it is sometimes hard to know if there really is consensus for these kind of infrastructure tweaks. But I believe there is at least no sustained opposition to changing the gcc-patches mailman setting as proposed above. So unless someone objects I like to make this change Tuesday September 19 around 08:00 UTC. And if there are no complaints at Cauldron we could do the same for the other patch lists the week after.
