Should submissions be prepared anonymously, like Technical Papers? How about accompanying material?
No. The review process is single blind, which means the reviewers will know who the authors are, but the authors will not know who the reviewers are. The submission has to be one page long, in final format, including the names of all collaborators on the work and their institutions. Accompanying material should include videos, additional results, tabled data, etc. But it should not be used to extend the explanations given in the one-page submission. Reviewers will be asked to reject such submissions without review. Please see also question 18.
