Would've been nice to have been given the opportunity to respond to Jakub's email before that decision was made. Not all of us are in the US timezone. (Jakub's email came in gone 1am my time.) -- RMK's Patch system: https://www.armlinux.org.uk/developer/patches/ FTTP is here! 80Mbps down 10Mbps up. Decent connectivity at last!
