One of the biggest advantages, I thought, to buying a book in PDF form was the fact that it would be updated when official Errata has been released. The first few books that I bought were from DriveThruRpg.com which appeared to expect products to be updated (options for email notification etc), but I still do not see that any product has been updated.
Is this something on Catalysts' end of things (updates are not being provided)? Or should I be emailing the site (updates are available but not being posted)?
