It seems I can’t post in “https://groups.google.com/forum/?fromgroups#!forum/ros-sig-ng-ros”.
So I assume that page is only for browsing and that for creating new Topics I must use this one.
Am I right?
Yes please use the Next Generation ROS Category to continue ROS 2.0 discussions. I’m going to recategorize this and the other thread you started.
My apologies and thanks.
