The RESEARCHERS.ONE platform offers to options for users to seek feedback on their work. One is the private or traditional peer review option and the other is the public peer review options. Details about the specific options can be found in The RESEARCHERS.ONE Mission as well as on the "Public versus private peer review?" FAQ page.
Both of these options are novel---the public peer review option requires authors to advertise their own work in order to get feedback, and even the traditional private peer review options requires authors to request reviewers themselves--- so it is natural that authors would have questions about how to navigate this process. A YouTube video where the co-founders share their thoughts on this is here.
