Two things about gadget submission.
1. When you submit a gadget you get two fields for files. The first is for a thumbnail, but the second one requires a ZIP file and it doesn't say what the ZIP is supposed to contain (at least in FF). So wht should it be
2. I just submitted a WebGadget and it was rejected, sadly I didn't get any info as to why it was rejected so if somebody could get back to me on that I'd really appreciate it, since I can't fix things without any info. (It's definately not an IP problem, I wrote the game myself).
Here's the gadget url:

Submission - what's the second file? Rejection reason?

Yes, the gadget documentation is a little messy. It's also a beta (version 0.7, I believe). Most of the samples haven't been updated since they were created way back in late 2005.
As for "submission guidelines" on the page I linked, that's the "check list before uploading your Web gadgets" under "Web gadgets". From the site:
