It's really just to prevent people from flooding the group with every picture on their page as some idiots will occasionally try to do. Frankly, getting ANY new posts to this group that I didn't make myself, much less featuring art made especially for it, is pretty rare. When I started this project on the Yahoo groups in 2007, I got dozens of posts for it every year. People were really enthusiastic about the concept. That enthusiasm has waned oner the last decade+, especially after the world made the shift from email-based posting to social media sites like this one. After moving the project here, participation dropped significantly. I finally had to stop offering an annual prize due to the lack of entrants. Now even the regulars rarely draw for it anymore. Honestly, seeing someone new come along who's excited enough about the project to actually draw new art for it would be really exciting.
