One of our readers was noting that some questionable, even offensive, advertisements were coming up in the comment box.
I've now paid to have the account upgraded and my understanding is that should get rid of the advertisements as well. Please let me know if that has not happened.
You will also notice that I have added a graphical banner at the top of the comments box, which not only includes the NLM banner, but also a reminder about the NLM rules for commenting:
"Critique Principles not People. Be Discriminating but don't Nitpick. Be Academic not Acerbic. Be Principled not Polemical."
I didn't realize that a banner could be put at the top of the comments until looking into the advertisement issue, and it seemed like a good place to not only place our "branding" but also a reminder about the tone we want to set in our comment discussions.
