New policy: if you want to complain about PsyArxiv (a free service that didn’t exist 15 years ago), you must sign up to be a moderator.
Due to a recent influx of problematic submissions, PsyArXiv has switched to pre-moderating its content. If your submitted preprint had not yet been approved, it will be temporarily inaccessible to the public (you can still view your preprint when logged into your OSF account). #PsychSciSky

Meta-analysis forest plots begin to look too crowded if you're reporting around 50 effect sizes or more. This 'orchard plot' is a really nice alternative for visualising 50+ effect sizes (paper link: doi.org/10.1111/ele....).
