Feel free to revert any copyediting I do. If I support on prose at FAC and list a few potential problems, I'm usually done at that point. It's up to the nominator(s) to decide how and whether to respond, and up to the reviewers and FAC coords to decide whether any remaining problems are a barrier to promotion. I'm only checking the main text, not images, infoboxes, end sections, links, or hidden codes. My reviews cover a range of issues that are concerns at FAC, but not some of the tougher problems, including contentious word usage. I try to set aside my personal preferences on what articles are supposed to say and how they're supposed to say it, so that I don't interfere with the writers and reviewers who like to tackle those questions.
