I've been trying to upload two screenshots but they are not going through it seems. They meet most of the requirements set, and are not offensive in any way. When I hit the submit button, it sends me back to the main page with a different URL, as if the screenshot was sent. Currently using Mac OS X 10.4.11 and Safari 3.1.2.
EDIT: Tried using FireFox just now and it worked fine. Must be a problem with Safari.
