It looks like we ended up with about 329 submissions. (Hopefully that won't change much at this point.) That's between 40-50 papers per PC member at 3 reviews per paper.
Thanks to everyone who withdrew the papers they weren't submitting. Otherwise, I had to go through and withdraw them manually myself.
Thanks to Shai Halevi for continuing to help me with the reviewing system.
Yes, I did get mail from about 10 people who hadn't known they'd need to file an abstract the week before, and I accommodated them. I think this should become a standard and everyone should get used to it. Again, keep in mind there's 40-50 papers per PC member; anything that makes their work easier is a good thing. (And Shai's interface for choosing preferences lets you see a paper's abstract pop up with a mouse rollover, so it's really nice to have abstracts early!)
Assuming things continue to go well, expect e-mail from PC members asking for you to handle a subreview before you head off for Thanksgiving....
