Group contests anyone?

I wanted to see if anyone is interested in having contests. A theme or scenario would be picked for an illustration. After a period of time, say 3 weeks or a month, the deadline for entries. We could have a group vote and the one with the most votes is the winner. I am still working on the prize, maybe the winner's illustration gets to the groups avatar for the month. I would love feedback on this let me know what you all think!
