LOL. I didn't catch that UI glitch in window sizing. I would most definitely change that to place a login next to each sign-up -- can clearly differeniate this with color, line, etc.
I find it strange that it's so hard to find the actual log-in option when visiting evernote.com. Massive real estate is given to signing up, which is understandable. But why not give current users an easy option to log-in? What is the rationale for this UI decision?
