i got the proofs for our neuroimage paper a couple of days ago, and was slightly disgusted with the number of errors that remain in it even after the copy editor had (supposedly) done his job. i may not have mentioned this on here, but after i gave the thumbs-up to the final version, one of our co-authors (who shall remain unnamed) took it upon himself to make a few "improvements" just before making the submission. there's nothing egregious -- a few omitted and extraneous words, and some stylistic clunkers -- but it annoys me that i should still have to make those corrections at this late stage of the game. there should be a rule in collaborative writing where one, and only one person is the grammar guy, and that person gets to be the last guy to touch anything before the final version is locked down. and by 'one person', i mean not the native chinese speaker who doesn't believe in indefinite articles.
