 All right, well, the Knowledge Cafes are based on a collaborative meeting methodology, which is called World Café in Origin. And the idea is to enable a whole bunch of people, many, many people, to engage in collaborative conversation together in a very short time and generate lots of ideas. So there is a design, many design principles to it. There's a methodology behind it. It's very complex. But in the experience of the participants, it looks like a café. They're seated at small tables of four, and they have topics, questions on which they have to discuss for about half an hour for each conversation round. And then we get them to move and meet new people. And so it's this sort of cross-pollination of ideas that at the end generates many, many ideas, and it gives the people a feeling that they've really been able to express themselves and create a content together. I started to introduce this in ITU a few years ago as an internal tool for department meetings. And immediately it was deployed across our meetings with delegates. And it's been very, very popular. And specifically for WISIS, this is the fifth World Café we've done. We started in 2013 with these knowledge cafes to enable this multi-stakeholder mechanism to express itself also through core conversations.
