Satisfaction of participants with CYSS 2020 was generally high as was monitored by a postconference survey (Figure ). However, some distinct points of improvement can be made out. Even though participants felt that they could connect to people they did not know beforehand, the overall opinion was that networking differed from on-site conferences (Figure ). It has to be emphasized that the question did not ask whether it was worse or better. As networking is one of the main aspects of a scientific conference, this needs to be addressed. Similar to on-site conferences, online meetings could also offer social, but digital activities. For example, a virtual "pub quiz" could be organized, where interested participants are organized in randomly selected groups and interact with previously unknown people, and in which questions are asked from the topic(s) covered by the conference. Alternatively, depending on the conference's audience, online computer games could be played jointly in small groups, such as Among Us. While not replacing on-site socializing, such programs could greatly enhance the online conference experience. Additionally, virtual meeting rooms such as Mozilla Hubs (hubs.mozilla.com) present an interesting option for providing networking opportunities at online events. Finally, central Q&A sessions with the invited speakers could be organized, during which participants can ask both scientific questions as well as for career advice in their respective field. While a majority of participants would also visit a next iteration of CYSS irrespective of the format it takes place in, a purely online format is the preferred way (Figure ). Notably, a purely offline format appears to be the second most-preferred format, while a mixture of both on-and offline seems to be met with reservations. It did not come as a surprise that a purely online meeting would be the preferred choice, as it allows participation to the conference irrespective of travelling costs, which is advantageous for international participants. "Mixed" conferences, on the other hand, are met with more scepticism, probably because such formats have not been implemented widely in the chemistry community as of now Figure . Evaluation of the post-conference survey (n = 30). (A) Participants were asked for their level of satisfaction from 1 (lowest) to 10 (highest). For the Mattermost platform, 6 participants responded that they did not use it. Data is presented within a median box plot (IQR: 25th -75th percentile box, median line, standard deviation whiskers, mean as cross) with only outliers presented as data points. (B) Participants were asked whether they agreed or disagreed with the statements. (C) Participants were asked if they would visit a future iteration of CYSS if it was purely on-site, purely online, or a mixed form (which was not further described).
