STICKY

  • Triage duty: Kershaw

  • 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
  • strange rendering problems?
