Calling All Freelance Designers!
This info is from Kam's Blog, which means you've probably already read it since everyone who reads Choose Death reads Pens and Swords. (Of course, the reverse is NOT true.)

Regardless, Wizards is hosting a rolling open call for short d20 adventures. No deadline + short word count = great chance to get published by the big guys.

I'm overbooked at the present, but I heartily encourage anyone with a little spare time to design a quick adventure. You could do it this weekend and submit it on Monday.
