We aim to promote an ethos of supportiveness and kindness at the EPCN meeting. Thus, we encourage conference participants to ask questions in a constructive way and to save any severe science criticisms for another occasion. We also wish to discourage the issuing of comments and long-winded questions or multiple questions. Overall, we plan to make the 2021 EPCN conference a fun, informal and inclusive event, which will entirely celebrate European ponds. This is the most important thing.
