Hi Florence, that looks amazing!
I love the idea of having the space for questions on the right. It will allow for if there are lots of questions following one speaker, and none or just a few for the other. And even if there are no questions, it may allow for summary or common themes to be pulled together.
I’d love to see an image of your finished product if that’s possible….? Or maybe if there is a Twitter feed or hashtag we could take a peak at?
