Hello Everyone, We have two goals with their champions ready for review. Please review and provide your feedback on Gerrit. 1. Add goal for project specific PTL and contributor guides - Kendall Nelson - https://review.opendev.org/#/c/691737/ 2. Propose a new goal to migrate all legacy zuul jobs - Luigi Toscano - https://review.opendev.org/#/c/691278/ We are still looking for the Champion volunteer for RBAC goal[1]. If you have any new ideas for goal, do not hesitate to add in etherpad[2] [1] http://lists.openstack.org/pipermail/openstack-discuss/2019-October/010291.h...
