Hi all, RIPE87 is coming up: the meeting will take place 27 November -- 1 December. Once again, we are seeking your presentations for the next MAT WG session, scheduled on Tuesday, 28 November! Presentations for the WG session are preferably 10-15min long. Please include in your proposal: * a title * a draft copy of your proposed presentation, even if just an outline * a paragraph describing the topic, and why the topic is of interest for the community. Interesting topics include (but are not limited to): recent measurement research which has an operational impact; recent operational work that may open avenues to research; projects, tools, or datasets that support either operations or research. Please submit your presentation proposal by **Friday, 27 October** by emailing us at mat-wg-chairs at ripe.net. We will make our selections and post the agenda soon after. RIPE meetings are fully hybrid with sessions facilitated through meetecho; we encourage presentations from anywhere. For our planning, we'd appreciate it if you can indicate whether you are likely to be online or on-site. Please ask if you have any questions regarding the setup on either side. Thanks! Nina, Massimo, Stephen, as WG co-chairs
