Sorry, but "Contribute" is as clear-cut as the "Edit" button (the new button just isn't in an organized dropdown, which was one extra step in the process as well). It may seem a little hidden, most likely because the button doesn't match a wiki's button color.

At least there's no additional whitespace.
