It auto-pops up a sign in link to Google when I visited it on Firefox, and it looks like it does the same on Chrome except Chrome blocks the pop up. Definitely fix that because I got a real sketchy feeling when it asked me to sign in upon immediately entering the page, not even clicking anything.
I think there was an update either at google or firefox recently because a ton of websites have started behaving like this for me seemingly out of the blue.
