Just popped in to say the link works and begins a download of the PDF automatically. Made me worry for a sec, and there were some weird numbers on the download size (downloaded more kbs than were written as size of file). At first I was afraid you were some clever spam-bot giving us bogus links to malicious downloads. Avira AV thinks your file is OK though, and the file is indeed a PDF of a book on sound for games. So for now, this seems legit...
TL;DR - Seems legit, as far as I could tell.
Thx man.
Haha yeah I was afraid I'd seem like a stingy spam-guy of some sort. Thanks for confirming it for me :D
