Thanks for the kind words, everyone, and the overwhelmingly huge response in term of the number of downloads. Wow! I hope a lot of folks get a chance to try it in play -- don't forget to look for the two free starter scenarios on our website.
About PDFs: Our general policy is to put out of print books up as PDFs, but it's limited by which ones we have digital files to work from. Thus the only ones you see on RPGNow were published by Atlas or WotC. So even when Mythic Europe (published by White Wolf) goes out of print, it's not likely to be PDF'd in a hurry, since it would require scanning and all.
