I encountered the same issue as well, but finally found a solution. Apparently LL has no idea what web standards are. The page does not display a submit button under Firefox, Chrome, or Opera on Windows or Linux, but when I view the page with Internet Explorer (yuck) in Windows, it works fine. The problem is entirely in the coding of the page. I have a hunch what browser their lead web developer uses. Probable Solution: If you're on Windows, try IE. If you're on MacOS, Linux, or BSD... install Virtualbox or something, then emulate Windows and IE.
