Don't sweat the changes man, it's what I do. I proofread papers I submit several times and yet I miss tons of things when I get them back so you aren't alone.
Don't take my comment the wrong way either, it was just meant to let you know there were some things to clean up, not to degrade/make fun of you. You're guides are among the easiest to publish by far. Keep up the good work and I look forward to your future submissions mate.
Sorry for the trouble. I looked over it a few times before submitting it. Guess I missed a few errors. I will make sure it does not happen again when I submit another G&R. Thank you for fixing them. Looks great, and I noticed some of the changes.
