I discovered the Intel Perceptual Challenge website, but find that "Challenge" applies mostly to using the site itself instead of the actual contest.
Please consider this constructive user input, I don't mean it to sound like I am complaining about it. I'd have posted this somewhere else, but I don't know where else I can, as there are no contact listings on the site.
1. We are required to submit an image, but there is way to do this in the form. Also, there seems to be some content limitations that will stop the "save" button from working, but there are no messages to explain exactly what needs to be changed.
2. Also, it doesn't appear to save the Youtube URL or the URL below it.
3. It pretends to let me edit a submitted submission, but in the end won't save my updates. (I saw the warning of submit=fixed entry. Can I delete an old one if I revise it?)
4. Oh yes, and there's no way to recover a lost password.
Thanks for the contest and good luck to all!
