First of all, please let me say that I'm not 100% sure that this is the right section for this post...! If it's not, please tell me where to re-post it and I'll happily do that!
Anyway, I was just on the "Giveaway of the Day" website, where they're giving away "Cover Commander" for free. It's no substitute for professionally produced e-covers which I know some fellow Warriors produce, but it's a start if you're on a limited budget!
The link is Giveaway of the Day - free licensed software daily. Cover Commander - Cover Commander creates professional, custom-designed virtual boxes, books, dvd-boxes, manuals, CD disks, and screenshots.
The only catch is that there's currently only 13 hours and 19 minutes left to download it....!
