Put it this way........
If we have one entry per person then we get to see nice work, WIP's of that work and possibly a free objects for us to download.

Now, if we can have more than one entry, for those that work faster or those who have more ideas they want to express, and not because of spamming the challenge with ones own ego, we get more nice work to look at, more WIP's and perhaps more freebies to download from Free Stuff.
