### Share something that you learned or liked :+1:

### Share something that you didn’t like or would like us to improve :-1:

- (Helene Hoffmann) I would like to either be able to ask questions inbetween, because if I can't understand something right in the beginning I have no chance to follow the rest of the talk. Alternatively, the talk could be provided as a video beforehand so I have the time to find out the things I don't understand myself and have the oppertunity to actually learn something.
- (PS) this is an interesting idea. This would be an inverted seminar so to speak. Everybody is expected to watch a prerecorded video and then we focus the time online on a discussion.
