Smashwords is a small company compared to Amazon or Barnes & Noble, and sometimes it shows. Right now they appear to be having some server issues. I was trying to look at my sales numbers and I got a Server Overloaded error. After several minutes I tried and got in okay, but when I tried to see my dashboard (where free and sample downloads are reported), I got a weird, badly formatted version of that page.
Well, with any luck it just means they're updating their retailer info. Here's hoping!
