Dear Colleagues of the Organizing and of the Scientific Committees, Invited Speakers, MDPI employees, and most of all, dear Attendees, WEF-1 2020 has come to its conclusion.

Despite the very complicated situation in which we were placed by the persistence of the COVID-19 pandemic, through much effort and much dedication from all parties involved, we succeeded in running a successful conference. Originally, our target was to have approximately 100 presentations. The final number was 37: given the circumstances, and especially the short advance notice given to the authors, I think we can be satisfied. We have made every effort to make the submission/reviewing procedure smooth and speedy, and we express our special gratitude to the anonymous reviewers who have devoted their precious time to assess for us the quality of the submitted manuscripts.

We have also learned a lot from this experience, and if—hopefully not—in the future, similar circumstances should force us to go for an entirely online conference, we are now better equipped to tackle the different tasks required by such a format, hitherto unfamiliar to us. I hope that the authors will be satisfied with the outcome, especially those who were awarded the Best Paper and the Best Oral Presentation Awards. Since the quality of our reviewing process was very demanding, I encourage all of you to submit your manuscripts for publication in the Special Issue that will be dedicated to our Conference: of course, these manuscripts will undergo a novel review process, so perhaps it is be advisable for all authors to submit a slightly revised version which takes into account both the latest reviewers’ recommendations and their own experience in presenting the paper.

Again, thanks to you all. A special thanks goes to my colleagues Prof. Roberto Melli and Roberto Capata, who shared with me the heavy load of the organization. Of course, we also extend our gratitude to our invited speakers, Prof. Özer Arnas, George Tsatsaronis and Dr. Frank Caro: I have already suggested in one of my addresses to treasure their presentations and use their contents to advance in your academic profession.

Substantial support for organizers and attendees was offered by Sara Martinez, Ana Sanchis and Stella Mao of MDPI without whom this conference would have never happened. The preliminary agreements on the format, details, target, and the topics were decided together with Dr. Frank Vazquez of MDPI, to whom also goes my sincere appreciation for his professional and pragmatic approach.
