Are there any non-trivial CodeIgniter apps out there?

Hi:

Yeah, I was more interested in making sure that there were commerical apps out in the wild; that CI was suitable for that type of site, and Iván gave me some good examples.
My app won't really be Groupon-like, but I am curious to see a full-fledged app from the "other-side." Thanks for the offer. I'll PM you.
