Interesting work. And a good job for people.
However I will say, just as a nod to the good people (at least some are good people) who own/dispense CS stuff, that if affordable, one should pick up a "REAL" sourcebook as well
Just 'cause they're out of print, I still see them for a decent price, and if it's still available, I'd as soon ensure that a COMPLETE free replacement for them not be made officially from this site
If the stuff will be a complete replacement of official sourcebooks with complete scanned in PDF copies of the books, I'd appreciate it being kept to PM/private emails. If it's material containing no fluff, but strictly for the rules in the books, those are fine.
Sorry, just a slight bit or paranoia with the new emphasis on copyrighting and piracy.
