Had the same problem when I accessed Evernote on a Win 10 machine on Chrome. Was able to select all the text and make Verdana. Gotham still looks just the same. Would be nice if they fixed this. What kind of sucks though is ALL my other notes I made in Evernote using Gotham on a Mac for the last 5+ years look poor on a PC since they were written with Gotham. I bounce between platforms, one of the awesome things of Evernote, but if this keeps being an issue I may swap over to Google docs...
You should add a button for existing users to log in below the signup button. I have to click the sign in link on top even though Chrome has auto-populated the login and password area. Its not a big deal but just annoying that I'm prompted to sign up every time I visit the site
