STICKY

  • Triage duty: SC
  • new untriaged bugs: https://tinyurl.com/zhk9yjf

  • NECKO NEXT bugs: https://tinyurl.com/zjwjfee
  • NECKO-BACKLOG bugs: https://tinyurl.com/hpkcxx3

Round Table:

  • Proposal: once at month (whichever triage cycle includes the 1st of the month), we have two triagers: one regular, and one person goes over the necko-backlog|next|active lists
    • look at active just to make sure they're all assigned
