I'm adding some project tags to allow others to find this task when searching in the corresponding project(s).
@SandraF_WMF: If you plan to work on this task, feel free to set Add Action... → Assign / Claim to yourself. If you plan to work on this task in this quarter, feel free to Add Action... → Change Project Tags and replace the Developer-Relations project tag by Developer-Relations (Jul-Sep 2017). Thanks!

Sandra, I recommend scoping this a little more, as this is going to be something you'll always deal with, while with tasks, we mean activities that have a purpose and a timeline (be it monthly, quarterly etc.).

@Elitre I'm probably going to close this task. I don't need it for ongoing maintenance of adding and archiving discussions, which is primarily where we are now. It's to be part of my workflow for the task at hand.
