At the top write: Title of the preprint, authors, date of submission, version number, preprint server, and digital object identifier (DOI)Start a new document and invite to your preprint journal club others who want to collaboratively write the preprint review – they will have to sign up on PREreview to be able to edit. Below are a short list of questions that you can have journal club attendants answer (PREreview short participant worksheet, example here), followed by more detailed guidelines on how to structure a more formal and complete peer review (PREreview peer review, example here). Answering the first set of questions will be faster and still povide useful feedback to the authors. However, if the main purpose of the preprint journal club is to train early-career researchers on how to write a peer review, recommend you write the full review as if you were a reviewer for a journal. You can use the comments from the first one to construct the preprint peer review. After you are done writing your your PREreview, you can click on "Document" (top left), "Publish" so that your preprint review will be public and will be assigned a DOI that you can use to advertise your review on social media, email to the authors, and post on the comment section on the server that hosts the preprint you chose for your JC. Additionally with a DOI, your preprint review will be citable! If you got this far, GREAT JOB! Thank you for supporting open science and helping science move forward faster!
