[Qgis-psc] Request for appointing a formal release "traffic controller" role

[Tim Sutton]

Hi

+1 from me to do this using the wording of your original proposal below. Just not sure who will be the person? Can we assume that you are volunteering Nyall? In which case I would propose to just appoint Nyall following the principle of using people who are actually motivated to do things :-)

Regards

Tim
