Fergus, my email to you in 2011 was from my general email address; after
becoming an editor here in 2013 I started emailing you from the address
listed in my Personal Information page.
I can see what you mean about the width of the comments. (I noticed it
when I made the change, but dismissed it.) I could enforce a max-width,
but if you want to design a nice background for the resulting margins then
I'll leave it to you: design is not my thing.
