    Context We had low turnout on the meeting on 5th August 2026, as we really need input from other taskforce members on what our next 12 months will look like, we will be having an interim meeting. This will be added to the W3C calendar shortly. When August 19th, 11am EST / 5pm CEST Agenda: Introductions, if necessary Brief Funding Update (5mins) Scoping the next year: Proposals Interaction Controls — replies collection usage, per-object reply controls, interaction controls, and consent respecting quote posts Suggested Milestone Items Issue Triage — lets look to see any other "obvious" candidates for work items (e.g., suspended, or some of the initial report items NOTE: This isn't a meeting to discuss implementation details, instead it's planning, as I need to get back to NLNet with a grant MoU soon. I will be moved the meeting along if we get too in the weeds. Outcomes: Each item should have a minuted vote for inclusion/exclusion, voting is -1 to +1, with -0/+0 as negative but no objection/positive no objection. We support contributions to the Agenda, please comment if there is something that we need to address during the meeting. Administrivia: IP Protection Note Reminder: Anyone can participate in these calls. However, all substantive contributors to any Taskforce Work Items must be members of the Social Web CG with full IPR agreements signed. https://www.w3.org/community/socialcg/join To contribute to Work Items: ensure you have a W3 account: https://www.w3.org/accounts/request, and sign the W3C Community Contributor License Agreement (CLA): https://www.w3.org/community/about/agreements/cla/ Reminder of Code of Conduct Scribe volunteer(s)? If we can't find a scribe, I'll need to record the meeting and use AI/ML to prepare the meeting notes, or the meeting cannot proceed. You can find information on how to join the meeting in the SWICG calendar

    4chan has people hiding their identities and being nazi fucks. Xitter has people showing their whole face and location, calling for the death of trans people. Xitter is IMO by far the worst. Screenshots from that place should be banned across the fediverse.
