It's up to you of course, but you
could use the same background graphic for all the months, so all you'd need to change would be the smaller graphics (the month titles). You could even use the same background for each of the month titles, just changing the name of the months. Not sure if that would hurt your chances with the judges, but it would be a good way to get in the running.
On the submission form, that's a bit of a sticker. As we understand it (at least in the US) your signature is only "legal" on paper, a fax, or if it's collected by an electronic signature device (such as many retail stores are switching to) including the Pocket PC, Tablet PC, etc. A scan of a signature as part of a document doesn't appear to be covered. Perhaps the powers-at-be thought it would be too easy to forge a scanned signature. It's interesting that they do consider faxes to be legally binding though, which (at 200dpi black and white) would seem far easier to manipulate than a 600dpi color scan for example. We're still investigating this and if anyone can show us a reputable source that states that this type of signature would be legal we would certainly allow it.
The form can also be sent via postal mail to:
Dell AXIM Contest
Virtual Office Systems
PO Box 48402
Ft. Worth, TX 76148-0402
We could accept a scanned document as long as it was digitally signed. This would also be a legal signature. Guidlines on the laws are available at the American Bar Association:

Good luck in the contest!
