Looking for a Chicago Roommate

Hi,
I'm moving back to the States in August, and I'll be a graduate student in Chicago. I'm currently using Craig's List to find an apartment, but I'd really like to live in a WG-type situation. It's hard to do the search from so far away, considering I can't meet potential flatmates or see the potential apartments. After spending a year in Tuebingen, I was thinking it might be fun to live with either someone from Germany or someone who had spent some time in Deutschland. If you're interested at all, please feel free to write me a quick note - after all, it's always cheaper to split the bills. :)
Oh, and I'm a 22-year-old non-smoker.
