I have a suggestion to add to the final version. In the help section, the settings page, I'd ask that you expand on the update URL a bit. I just spent the past 30 minutes looking through forums and wiki trying to figure out how I'm suppose to type the URL to my site and the update.php. The physical file "update.php" is in a folder called "pages" and this folder cannot be accessed directly. I found other suggestions that I use /admin/update.php, but that didn't work. Finally, I found a post that was nearly a year old stating to use ../rosterpath/update.html. That DID work...but the information was hard to find, and not consistent throughout the uniuploader forums.
Just a suggestion/request.
EDIT: Nope, that didn't work either. The debugger doesn't give me any errors, and the server response screen seems to be doing all sorts of stuff, but nothing changed on the roster. I'm sure it's just a setting on my end, but until I'm sure on the URL, I can't check any of the other settings.
