When an article has passed open review, a notice is sent to the relevant (American English or British English) copyediting mailing list inviting copyeditors to sign up to copyedit the article. The author must then select two copyeditors for the article and must also decide whether to make copyediting changes or to choose a copyediting proxy to do so. Then, again on a specially-created web page, the copyeditors, serially, offer their comments to the author who then makes appropriate changes; alternatively, if a proxy was chosen, the proxy simply makes changes to the article directly, and the second copyeditor gives comments to the proxy. When both copyeditors have approved the copyedited draft, the article moves on to the open copyediting stage.
