We have been working on a new HTML5 version of the uploader, and it is now available in beta if you’d like to try it out: http://archive.org/create/ (look for the Beta Uploader button).
The new uploader is capable of uploading much larger files than the old one, and you can add a wider variety of metadata if you need it. Please note that the beta uploader does NOT work in Internet Explorer due to the limitations of that browser. We recommend Chrome or Firefox for the best experience.
If you have comments on the beta uploader, please reply in this forum thread.
