umm.. why?
If I was the person that developed this, I would have spent <$25 on themeforest.net and tossed up a simple splash page with a call-to-action button and a short description of what it does. No one in their right mind is going to blindly hook up their dropbox to a blank site.
I don't mean this is a nasty way, but with a single page which basically says, "can I access your data please?" and no explanation I can't understand who would upvote it?
I have no reason for giving you access to my dropbox account
Oh and I use Google Drive instead of Dropbox.
